Not a wrinkle mars her perfect porcelain visage, nor is there a blemish on her suspiciously silky skin, while her adamantine hair defies all laws of gravity.

Welcome to the distinctly odd world of Callista Gingrich, 60, President Donald Trump's Ambassador to Switzerland and Liechtenstein, where any inkling of imperfection has been banished to Instagram hell.

In her latest video the diplomat appears like an ethereal vision, digitally superimposed on a background of a soccer stadium, encouraging Europeans to travel to the World Cup.

'We look forward to welcoming you to the United States,' she intones rather ominously, her lips set in a fixed beatific grin.

The video has been widely mocked online and given impetus to a burgeoning internet conspiracy theory that she could be a creation of Artificial Intelligence.

'Great video, you look absolutely normal and human-like,' replied one X user.

'Is she speaking to us from Heaven?' inquired another, who thought she looked a bit like a celestial being.

Of course, the ambassador is very real and, last week, was on the airport runway in Geneva, standing with two Pontifical Swiss Guards in red capes to greet President Trump as he arrived for the G7 summit. 

That appearance, however, only led to yet more online speculation, this time about her magnificently indestructible hair.

While President Trump's carefully combed locks were flung into chaos by the rotor blades of a waiting helicopter, Ambassador Gingrich's perfect platinum blonde bob never wavered a millimeter in the hurricane-force wind.

It is unclear what she and the president chatted about on the runway. Perhaps he asked for the brand of her hairspray. Whatever it was, he then unexpectedly invited her on to his helicopter for the flight to meet other world leaders in nearby Evian-les-Bains.

President Trump is clearly a big fan, having nominated the MAGA stalwart as US Ambassador to the Holy See in 2017, and later her current post.

He has lavished praise on her for 'defending international religious freedom, combatting human trafficking, and provide humanitarian assistance around the world.'

One diplomat who has interacted with her told the Daily Mail she was 'very prim and proper from our interactions.'

However, she remains something of an enigma, according to some former and current European diplomats.

One described her as 'wrapped in mystery,' while another said they mainly knew her for having an 'impossible helmet hair cut with a severe modern angular cut that went out in the 80s.'

Another described the blonde simply as 'well coiffed,' even when doing her shopping.

All ambassadors go through the State Department's three-week Ambassadorial Seminar which is managed by the the Foreign Service Institute. Many nominees are from outside politics and new to the world of diplomacy.

One source who trained with Ambassador Gingrich said she was very helpful, having already been an ambassador in Trump's first term.

'I just remember her having good advice for the new ambassadors,' the source said. 'She was experienced and the others seemed to take her advice.'

Ambassador Gingrich's social media output first caught the eye in April when the US Embassy in Bern released a video for National Apprenticeship Week, which showed her dressed in bright orange against a blue background.

She has been dubbed 'Madam Smooth,' by some. 

'First human to take an AI job,' concluded one viewer, pointing to the growing difficulty of telling the difference between people and avatars.

Amid numerous comments about hallucinogens, another added: 'This is what the Teletubbies saw every day when the sun came up.'

'This is more terrifying than anything in the Resident Evil trailer,' wrote another.

Amid the frenzy, Ambassador Gingrich also received support online.

One follower wrote: 'I love how this woman edits the hell out of every single one of her photos, sits back as the entirety of Twitter roasts her over it, and just turns around and does it again, over and over and over. You do you, Cally!'

The ambassador's Instagram account has used AI content. This month, she posted an entertaining AI-generated World Cup video of George Washington scoring a free kick against the British redcoats, with Benjamin Franklin commentating.

However, the likeliest explanation for her own glossy appearance seems to be that she may have discovered social media's airbrushing features, and perhaps uses them a little enthusiastically.

In numerous pictures, including at an embassy podium in Bern, the ambassador appears mysteriously untouched by the hand of time.

On occasion, her husband Newt, the former House Speaker, seems to have been given similar anti-aging filter treatment.

'Beautiful Saturday in Neuchâtel with my favorite golf partner,' the ambassador wrote recently, showing her husband in a golf cart looking almost cherubic.

But, in other pictures, his well lived-in face is shown with all its natural character.

In March, Ambassador Gingrich posted pictures of the former Speaker's 82nd birthday weekend in St Moritz.

'Lay off the filters hun,' advised one follower.

'No filters for Newt I guess,' wrote another.

The filters appear to have been on for a picture of the couple with Secretary of State Marco Rubio a few weeks ago.

'Happy Birthday Secretary Rubio!' wrote Ambassador Gingrich.

But which birthday? Rubio, a man with at least four jobs and the cares of the world on his shoulders, looked strangely younger than his 55 years.

The State Department did not respond to a request for comment on whether the ambassador was using AI or photo filters. 

The diplomat's recent appearance on the runway with President Trump reignited discussion about her hair, which previously was a feature of the 2012 presidential election, when her husband ran for the Republican nomination.

At the time it was dubbed 'The Callista,' and divided opinion. It even had its own Facebook page. Enterprising journalists said that the style, complete with a 'swoosh,' took four hours to create.

Kellyanne Conway, at the time a pollster and strategist for Newt Gingrich's campaign, told the New York Times then: 'Men say, "I love your hair," women compliment her and then say, "How do you keep it so perfect?"'

Conway said Callista was a 'meticulous, polished person, and that is reflected in her hair.'

During the upheavals of a presidential campaign 'The Callista' was a 'proverbial anchor in the storm.'

Meanwhile, the secret to keeping the celebrated hairdo in place was revealed to be Kenra Volume Spray 25 hairspray.

However, during that campaign, critics lampooned it.

Kate McKinnon, playing Mitt Romney's wife Ann on Saturday Night Live, joked: 'If you think I’m unrelatable, check out Callista Gingrich. She looks like a character from Mars Attacks!' 

That was a reference to the character Martian Girl, played by Lisa Marie, in the 1996 sci-fi movie.

Gingrich is known to have used at least two hair stylists over the years.

One, George Ozturk, who ran the George Salon at the Four Seasons in Washington, passed away in 2022. His salon was known as a bipartisan destination where he also styled Nancy Pelosi.

Before he died, Ozturk advised that his client's hair 'has become so well-known that to change it now would be a big mistake for Mrs Gingrich.'

She clearly took that advice and nothing appears to have been altered across the years.

At one time, Gingrich also used famed stylist Andre Chreky, who styled Laura Bush's hair when she was in the White House. Chreky ran a salon a few blocks away from the White House, where he was described as an 'artist and visionary,' and the cost of his personal attention was listed as 'please inquire.'

The salon shut down a few years ago and Chreky was not immediately available for comment.

It is not known where Gingrich has her hair done now, but it seems she has found a stylist in Bern to keep it the same.

Chad Cook, creative director of Privé, told The Cut it must take up to 60 minutes every day to get the hair right.

'The secret is building support into the hairstyle rather than relying solely on hairspray,' he said. 'Proper blow-drying techniques, root-lift products, and setting the hair while it cools all create a strong foundation.'

Newt Gingrich long ago admitted that he had a six-year affair with Callista beginning in 1993 while he was married to his second wife Marianne. He became House Speaker in 1995 and ultimately divorced Marianne in 1999, marrying Callista the following year.

When he ran for president in 2012, his opponents accused him of hypocrisy for having had the affair in the 1990s at the time he was leading the impeachment pursuit of President Bill Clinton relating to Monica Lewinsky. Newt Gingrich rejected the charge.

His ultimately unsuccessful 2012 campaign also took a hit when financial disclosure forms filed by Callista revealed a line of credit ranging from $250,000 to $500,000 at the jeweler Tiffany & Co.

The future ambassador was born in Wisconsin and is of Swiss and Polish descent. Her name comes from the Greek word 'kalos,' which means 'beautiful.'

She worked on Capitol Hill in Washington before marrying Newt and the couple have made numerous political and religious documentaries.

Also a prolific children's author, she has penned several historically themed best sellers, including 'Hail to the Chief,' about US presidents.

During all her time in public life, one thing has never changed - her hair.

It has been, as a supporter put it, the 'one immovable object in a rapidly changing world.'
