Her own MAGA fairytale may have hit the skids after her split from Donald Trump Jr.

But Kimberly Guilfoyle was beaming with pride this weekend as her younger brother married the daughter of one of Donald Trump’s closest allies in a stunning wedding at Ashford Castle in Ireland, DailyMail.com can reveal. 

The newly-nominated US Ambassador to Greece, 56, was the maid of honor Saturday as Tony Guilfoyle tied the knot with Lyda Loudon, daughter of conservative TV personality Dr. Gina Loudon.

Energy drink exec Tony, 53, fell for Lyda, 29, after meeting two years ago on the ritzy Palm Beach social scene, where her parents are well-connected members of Trump’s Mar-a-Lago club.

The lovebirds picked out the historic Ashford Castle, a medieval landmark and five-star country estate in County Galway, because Tony’s late father Anthony grew up an hour and a half away before emigrating to the US at the age of 20.

Despite hiring out one of the premier wedding locations in Europe, the happy couple kept things ‘under the radar’ and ‘intimate’, an insider told DailyMail.com.

‘They wanted their wedding to be an incredible spectacle for their closest family and friends. It was all of that and more,’ the source revealed.

Guests were treated to several days of traditional Irish pursuits, including falconry, horseback riding, and clay pigeon shooting before attending Saturday’s ceremony, planned by elite wedding organizer, Olivia Buckley.

Lyda, who runs her own digital marketing company, wore a traditional, corset-style white gown in keeping with the regal, historic setting, according to our source.

She arrived on a horse and buggy before proud dad John William Loudon, 57, a former Missouri state senator, walked her down the aisle in a lakeside marquee.

The bride’s siblings Lily, 25, Jack, 23, and 18-year-olds Samuel and Bo – a young conservative influencer and childhood friend of Barron Trump – were all there to celebrate with their big sister.

Ronan Anthony Villency, Kimberly’s 18-year-old son with ex-husband Eric Villency, also served as one of the groomsmen, looking handsome and suave in a smart black tuxedo. 

And as a cute flourish, ring bearer duties were assigned to the couple’s adorable four-year old Shih Tzu, Charli – who flew to Ireland with them and, with the help of ‘professional wedding dogsitters’, was trained to carry the ring down the aisle on a specially designed pillow. 

A lavish wedding banquet kicked off with a spectacular firework display over the River Cong accompanied by Coldplay’s ‘A Sky Full of Stars.’

Then it was off to the castle’s pub, Cullen’s, where the pageantry made way for pints of Guinness, Irish dancing and folk music.

‘It was just the most gorgeous ceremony ever,’ gushed our source.

‘Kimberly was beaming the whole day. She was dancing, socializing, singing away with friends, loving every part of it.

‘Nobody was happier than her.’

Kimberly’s pals say the former Fox host has stayed on good terms with the Trumps, despite her split from Don Jr. and remains close to Dr. Gina, 57, co-host of the American Sunrise morning show on Real America’s Voice.

The two have been pictured posing together at various MAGA or charity events, including a recent benefit held at Mar-a-Lago earlier in March. 

The Loudons live in South Florida and are known as close friends of the Trumps, with the president’s youngest son Barron having close ties to Dr. Gina’s younger son Bo, an up-and-coming conservative influencer.

Kimberly made a triumphant return to the White House last week where Trump hailed the appointment and paid tribute to a ‘really great friend’.

‘Kimberly is in great spirits. This is a new dawn for her, this job will be incredible,’ a friend told DailyMail.com.

‘She’s in a very good place right now.’

Kimberly’s engagement unraveled last year after the President’s eldest son was spotted canoodling with his new socialite squeeze, Bettina Anderson, at a Palm Beach bistro in September.

Weeks later DailyMail.com revealed exclusive photos of the pair enjoying a glammed-up date for Bettina’s 38th birthday before heading back to her $860,000 townhouse for the night.

The new MAGA power couple became ever more brazen, attending ritzy social events, state functions and the Super Bowl together – despite Kimberly also being in attendance.

The former prosecutor and ex-wife of California governor Gavin Newsom still needs Senate confirmation for the Greek ambassadorship, which would send her across the Atlantic to Athens, but it’s considered a formality.

Built in 1228 on the site of a former monastery on the County Mayo-Galway border, Ashford Castle has hosted its own fair share of historic power struggles.

The castle was seized from the Anglo-Norman de Burgo family following a bloody battle with the Englishman Sir Richard Bingham, Lord President of Connaught, in 1589.

It was purchased by Victorian beer baron, Sir Benjamin Lee Guinness, in 1852 and extended into a 26,000-acre hunting lodge.

In recent times it’s been a five-star hotel and $15,000-per-day wedding venue for well-heeled VIPs and celebrities.

Famous guests have included President Ronald Reagan, US Senator Ted Kennedy, and actors Robin Williams, Brad Pitt and Pierce Brosnan.

Golf superstar Rory McIlroy married Erica Stoll there in April 2017.
