Actors becoming very emotional upon receiving awards is such a well-established trope that it's become the stuff of comedy.

But when Rosamund Pike, 47, did just this when accepting her Olivier award for best theatre actress last weekend - welling up in tears as she thanked her husband Robie for his invaluable support - there was something unusual at play.

Because, so low profile was her husband until this moment, few people in the audience and the public were even aware she was married.

This apparently included the camera workers filming the speech, because when an emotional Rosamund concluded 'Thank you Robie', instead of zooming in to get his reaction they confusingly cut to Cate Blanchett instead.

So just who is Mr Rosamund Pike?

The Daily Mail set out to answer this question and found that, for one who has so doggedly avoided the limelight, Robie Uniacke is quite the colourful character.

For one thing Uniacke, age 65, Robie is nearly 20 years Pike's senior.

For another, he isn't her husband. As the Daily Mail's Richard Eden recently revealed, instead the couple are 'happily not married'. 

She even joked about this during her acceptance speech.

'My partner is famous for whispering to a bridegroom before he enters the church: 'You are the only person who thinks this is a good idea',' she told the audience. 'He's always been a relentless truth-teller.'

And while Pike, as her demeanour suggests, is solidly upper middle class - she was raised in Earl's Court as the only child of two opera singers, went to £60,000-a-year Badminton School in Bristol and then Wadham College in Oxford - this is nothing next to her partner's society background.

Old Etonian Robie, born in Windsor, is descended through his father from an ancient family of landed Anglo-Irish gentry. 

His sister Camilla married into the multimillionaire Guinness dynasty: her late husband Jasper Guinness was the son of brewing heir Jonathan Guinness, 3rd Baron Moyne.

And Robie's first wife was the titled daughter of the Earl of Carlisle.

His mother, artist and fashion designer Sally Uniacke, who founded a boutique fashion label in the sixties called Cat Designs, passed away in a car accident when he was only around eight years old.

And Robie seems to have inherited her creative side.

He reportedly began a career as a City stockbroker only to abruptly quit to spend five years deep-sea diving for buried treasure; not the sort of career move one often sees mentioned on LinkedIn.

And while he may not have found a hoard of gold, he does seem to have discovered that office life wasn't for him and has worked for himself ever since, a serial entrepreneur. More of which later.

But he's also very much a hands-on father to their sons as we learned this week.

Because this was the basis of Rosamund's gushing tribute - which also saw her giving him a passionate kiss.

'The irony is,' she told the audience at the Royal Albert Hall. 'Here I am doing a play about the juggle of being a woman, being a professional working woman with a family, and a job. And the fact is, I'm only able to do this performance because I have a wonderful man at home who is looking after our children and that is the truth of it and the irony and Robie, thank you.'

The couple, who began dating in 2009, now live in a Georgian townhouse in a leafy part of Islington, north London, with their two sons, Solo, 13, and Atom, 11, whose names perhaps reflect their father's free spirit.

A neighbour told the Daily Mail: 'They certainly don't appear to have any airs and graces. You wouldn't know that she was an Academy Award nominee.

'She just seems completely normal. They just seem like a normal family.'

Pike bought the terraced property in 2012 for £1.6million – before the family then also bought the house next door, which they are currently renovating, for £2million in 2023.

It's unclear whether they plan to occupy both but their Grade II-listed status would make it next to impossible to knock them through if they did - which might result in the eccentric prospect of the couple having to visit each other via two front doors.

The family also spent five years, from 2019 to 2024, splitting their time between London and Prague while Pike starred in Amazon Prime fantasy TV series, The Wheel of Time.

Uniacke is also extremely erudite. As part of his parenting he taught himself Mandarin in order to make sure their sons learned it too - and the family often travel to China.

Indeed thanks to his dad's nurturing, Solo won a government-run Mandarin-language speaking contest for primary school students in 2024 – which saw him go viral in China.

Along with a somewhat chequered financial history, he also has had quite a complex relationship history with six children in total and two previous marriages.

Uniacke has a much older son, born in 1984, also called Robie, with Lady Emma Howard, that daughter of the late Earl of Carlisle. The pair married in 1983, when he was just 22 and she was 30.

Both later went to rehab for heroin addiction, before their divorce in 1988.

Uniacke was quickly remarried later that year, to interior designer and gallerist Rose Batstone who still bears his name years after their split.

She runs three upmarket shops, for furniture, fabric and homeware, just a stone's throw from Sloane Square, in Chelsea, as part of her brand Rose Uniacke.

The pair, who later divorced, had three children together, Olive, Hector and Florence – and she is now married to Harry Potter film producer David Heyman, living on a square in Pimlico.

Olive Uniacke-Ensley worked on the set of the final Harry Potter film as a PA and briefly dated its star Daniel Radcliffe.

Olive was educated at Gordonstoun School in Moray, Scotland, where King Charles is among the old boys, as well as at the French Lycee in Kensington, west London.

She is now an agent for WME, representing a range of glitzy clients including actor Riz Ahmed and actress Tessa Thompson – and boasting a host of celebrity friends.

Her Instagram shows snaps with singer Dua Lipa, actor Nicholas Hoult, socialite Poppy Delevingne, model Adwoa Aboah and Kardashian business partner Emma Grede.

And she has previously been pictured attending a host of premieres, awards and film festivals, from London to Venice, along with the Vanity Fair Oscars Party and the Baftas.

Her wedding in 2022, in the church local to her Pimlico family home, was covered by Vogue, with Valentino gifting her a bright pink suit and bralette to wear for the reception.

She now lives in Los Angeles with her Californian husband, mental health specialist Dane Ensley, who she also had another ceremony with in Las Vegas, and their daughter Ever Rose.

A friend previously told the Daily Mail of her youth: 'Olive is renowned for holding some of the best house parties, really great bashes. She can be quite wild.

'She loves to drink champagne, particularly Moet, and she chain-smokes Camel cigarettes.'

As well as his two ex-wives Robie's former girlfriends include fashion stylist Sophia Hesketh, the daughter of the former Conservative treasurer turned UKIP defector and ex-Formula One owner Lord Hesketh.

Ms Hesketh, who is thought to have been the first girl to kiss Prince Harry, was 24 years Uniacke's junior - 19 to his 43.

Lord Hesketh is said to have been so angry about her relationship with him that he offered a cash reward to anyone who would woo Sophia away from Uniacke.

Pike, meanwhile, was once engaged to British director Joe Wright, who she met when he cast her in the 2005 film adaptation of Jane Austen novel Pride & Prejudice.

But they split in summer 2008 just two weeks before their wedding, with Pike later admitting she had 'no idea' why: 'He was never clear about it. Part of what makes it so confusing.'

Wright was remarried to Indian musician Anoushka Shankar within two years – but the couple, who share two children, divorced in 2019.

He has been dating American actress Haley Bennett since 2017 and the pair, who live in Somerset, share a daughter.

In Pride & Prejudice, Pike played Jane Bennet, opposite Old Etonian Simon Woods as Charles Bingley, who she dated for two years when they were both studying English at Oxford.

They parted ways in 2002 but remained friends, after he came to terms with his sexuality.

He is now in a civil partnership with Christopher Bailey, the former chief executive of British fashion brand Burberry.

Her current partner, Uniacke, who has similarly starry friends, including actor Hugh Grant, has previously long been seen as eccentric but brilliant.

He was once called 'a mysterious loner and rare book collector who haunts South Kensington' in Tatler's Little Black Book.

And a friend previously told the Daily Mail he was a 'likeable rogue': 'He's a total scruff, but has charisma to spare.'

And Pike too has praised his intellect. She said previously: 'I have a very clever partner who's got a very astute mind and is very, very well read and articulate and ruthless about how something I do might play out on screen.

'My tendency is to identify with a character and imagine there is more on the page than there is. He's quite good at putting a check on that.'

Robie now co-owns real estate business Santi Limited with Pike, which owns their newer Islington property.

The firm is valued at £2,217,240 with £6,098 in other assets – but it owes £2,396,028, meaning the business is a whopping £172,690 in the red.

Uniacke also owns 80 per cent of the company shares in a firm called Primitive Streak set up in 2019 for 'other business activities', with Pike owning the other 20 per cent.

In 2024, the company had assets of just under £740,000, including £500,000 in cash – but it owed creditors £737,000.

By last year, its assets were down to just over £255,000 and it still owed creditors £253,600. The firm had just £850 in reserves at that time – which is now up to £1,744.

Uniacke also set up a management consultancy firm called Solus Rex Limited in 2021, but it was dissolved in 2024, with £59 in reserves according to its latest accounts from 2023.

Another business, an IT consultancy business called Pale Fire Limited, set up in 2010, saw him nearly on the verge of bankruptcy.

It was declared insolvent and later dissolved in 2016 with Uniacke owing a considerable amount of money – some £131,034 in an overdrawn loan from the business.

He offered liquidators £10,000 to settle the debt, which was rejected.

At this point, the receiver was sent a schedule of his income and assets, which 'provided that Mr Uniacke had no income and no physical assets'.

The liquidator said: 'I instructed agents to complete a wealth report to quantify Mr Uniacke's material net worth. The report confirmed that Mr Uniacke had no assets.'

He eventually offered to pay £25,000 which was accepted as it offered a better return than 'demanding repayment and petitioning Mr Uniacke's bankruptcy'.

It meant his creditors, mainly HMRC, who were owed £167,010, received just £11,684.49 – only some seven per cent of the debt that needed repaying to the taxman.

He may not have succeeded at every step but his life has never been dull.

And in her eyes, as Pike once explained, Uniacke is 'the most interesting person I've ever come across'.
