The BBC are busy setting up for The Celebrity Traitors as the iconic Ardross Castle in Scotland is transformed on Tuesday ahead of the new series. 

As the star-studded cast landed at Inverness airport, preparations for the hit series have officially got underway as the BBC crew transformed the remote castle.

Seven Land Rovers were parked at the front of the castle ahead of the stars arrivals. 

The BBC have reportedly been forced to double its £1million Celebrity Traitors budget for its second and most star-studded series yet.

The A-list line-up was officially announced when the broadcaster dropped the first teaser trailer over the weekend with the likes of Maya Jama, Richard E Grant, Jerry Hall, Romesh Ranganathan and Ross Kemp also heading to the Scottish castle.

The increased budget was already obvious as pictures emerged of the stars touching down in the highlands after travelling via planes and private jets, while last year many contestants were said to have travelled on the train.

Meanwhile the likes of Alan Carr and Sir Stephen Fry were also said to have been ferried around during last year's series in a minibus, which has now been swapped for chauffeur driven cars.

Money has also been spent on beefing up security to keep the stars safe and the castle's goings on under wraps ahead of transmission later this year.

A source said: 'Although most of the stars are British, so many of them are used to working in America that their teams are used to the treatment.'

They told The Sun: 'The production team have little choice, however, than to cater for their demands because they accept the number of A-listers taking part in this year's show makes it exceptional.'

The Daily Mail have contacted BBC for comment.

Maya Jama was pictured arriving at Inverness airport on Sunday afternoon, reportedly taking a huge pay cut to appear on series two of the BBC show.

Hours earlier Coronation Street actress Julie Hesmondhalgh and EastEnders star Ross Kemp, 61, also touched down, before jumping into their cars to head to Ardross Castle in the Scottish Highlands.

Singer James Blunt then followed on a few hours after.

Dressed down in a white T-shirt and cream trousers, Maya wore sunglasses and flashed a nervous-looking smile at airport staff.

Comedian Joanne McNally was also seen on the same flight, dressed in cycling shorts and also hiding behind some dark shades as she wheeled her luggage to the car.

Maya was reportedly the first star to be approached by Celebrity Traitors bosses in a bid to pull in a younger audience thanks to her Love Island hosting duties.

The 31-year-old was more than willing to take a huge £760,000 pay cut compared to her fee hosting the ITV dating show.

She is said to have taken the £40,000 rate after falling in love with the series while watching it with her boyfriend Rúben Dias.

A source told The Sun: 'She loved watching the first Celebrity Traitors series at home with boyfriend Rúben and is so excited to get filming. She can't wait to do some fibbing and be as deceitful as possible to try to win it.

'It has worked out perfectly that she can go straight from the Scottish castle to the villa in Majorca to film the summer Love Island series in June.'

The Celebrity Traitors series two cast was officially announced when the BBC dropped the first teaser trailer on Saturday, with Jerry Hall also seen heading to the castle over the weekend.

Shortly after the announcement, Jerry was spotted touching down in Inverness alongside Richard E Grant, Bella Ramsey and Amol Rajan, before jumping in cars to head to the Scottish Highlands.

After months of speculation over who could be following in the iconic footsteps of last year's winner Alan Carr, in a quirky new trailer the 21 names were finally revealed.

Also heading to Ardross Castle in the Scottish Highlands are Michael Sheen and James Blunt.

Comedians Rob Beckett, Joe Lycett, Miranda Hart and James Acaster will also be joined by Little Mix star Leigh-Anne Pinnock.
