Kimberly Guilfoyle puts on a brave face to accept Donald Trump’s Greece ambassador nomination after Don Jr.’s betrayal

Kimberly Guilfoyle officially recognized her appointment as US ambassador to Greece, as it became known that she and her fiancé Donald Trump Jr. stopped doing it.

The 55-year-old Trump campaign adviser said on social media shortly after the president-elect’s announcement Tuesday that she is “ready to serve,” but did not elaborate on her crumbling relationship with his son.

“I am honored to accept President Trump’s nomination as the next Ambassador to Greece and look forward to earning the support of the U.S. Senate,” she wrote in a message.

She added: “As ambassador, I look forward to delivering on the Trump agenda, supporting our Greek allies and ushering in a new era of peace and prosperity.”

News of Guilfoyle’s new high-profile role emerged as news that Don Jr.’s romance with another woman reached fever pitch on Monday – when he was caught holding hands with much younger Palm Beach socialite Bettina Anderson.

DailyMail.com exclusively reported on the budding romance in August, when the two were seen locking lips during a brunch date, but both Don Jr., 46, and Kimberly have remained consistently quiet about their relationship status since then.

“She’s obviously putting up a brave front, but she was crushed by Don’s very public betrayal,” a source told DailyMail.com on Wednesday.

“Once Don fell for Bettina, the writing was on the wall for Kimberly. The split was supposed to happen quietly after the election, but the Daily Mail photos put an end to that.

“It’s a pretty humiliating situation,” the insider added.

Despite the photographic evidence and mounting rumors pointing to their rift, Guilfoyle had remained on the ground as a loyal Trump campaign adviser in the run-up to the election and was photographed with his family at the president’s victory party last month.

But her presence at political events wasn’t enough to quell speculation as her notable absence from recent family events further fueled curiosity about the couple’s future.

In an apparent attempt to keep up appearances, Don publicly congratulated his estranged fiancée on Tuesday in an X-post that she then shared on her social media accounts.

‘I’m so proud of Kimberly. She loves America and has always wanted to serve the country as an ambassador. She will be a great leader for America First,” he said.

Three months after raising questions about his apparently cozy relationship with Anderson, Don Jr. confirmed. their romance virtually over the weekend and Monday night when he was seen celebrating her 38th birthday in Palm Beach.

A source confirmed to DailyMail.com on Tuesday: ‘There is no Kimberly and Don anymore – at least not romantically.

‘Their engagement hasn’t officially been called off yet. They waited until after the inauguration to make the announcement.”

The source added, “The truth is, Don and Bettina are still very much together. He’s crazy about her.’

Exclusive photos from DailyMail.com showed the two leaving a restaurant hand in hand after a celebratory dinner for the glamorous brunette.

The loved-up couple spent nearly two hours at the chic downtown hotspot Buccan, three miles from her West Palm Beach mansion where they spent days and nights, DailyMail.com revealed earlier on Tuesday.

Don Jr., dressed in a smart blue suit and white open-neck shirt, showed no qualms about showing off his new flame as they left the restaurant just before 10 p.m.

They came out with another couple and you heard Don Jr. laughing before saying goodbye to the others and walking across the street to his vehicle, completely in love with each other.

Anderson – dressed in loose, flowing black pants with a black vest-like top and carrying a maroon handbag with a gold clasp – stayed close to her husband as they approached his pickup parked directly across from the restaurant, with their fingers interlocked.

Anderson herself also dropped not-so-subtle hints of their romance, sharing photos of a romantic flower delivery to her Instagram Story, discreetly tagging her new boyfriend, @donaldtrumpjr, in the top left corner.

The photo showed a note with the flower arrangement on it: Many have said you’re getting older, but I think you’re perfect…happy birthday!’

Anderson responded to her friend’s post with a tongue-in-cheek caption, saying, “Tough but honest.”

Guilfoyle became engaged to Trump’s eldest son on December 31, 2020, but it was not made public until January 2022.

The pair started dating in 2018 following Don’s divorce from first wife Vanessa Trump.

Guilfoyle, a former prosecutor in San Francisco and former wife of Democratic Gov. Gavin Newsom, became a major conservative after landing a long-term role at Fox News in 2017.

She would quickly enter Trump’s orbit and become one of his political campaign advisors, while embarking on a sensational romance with his eldest son.

Once called the “prom king and queen of MAGA land,” Guilfoyle and Don Jr. Trump’s presidential campaign amplified with prime-time speeches at the National Convention in July and they appeared arm in arm at rallies across the United States, but the political love story would eventually come to a standstill.

Sources told DailyMail.com at the time that she was ‘blindsided’ when images of Don dining with Republican ‘it girl’ Bettina Anderson, 38, emerged late last summer.

However, just days after that revelation, Guilfoyle was spotted by Don Jr.’s side during his surprise trip to the Balkans.

Don Jr. traveled to Serbia and Romania to deliver the message that a second Trump presidency would end Russia’s war in Ukraine.

This followed another revelation by Daily Mail that Bettina Anderson was seen in a video chatting with the former president’s son, his ex-wife and their daughter at a party in Florida, while Kimberly was nowhere to be seen.

Sources close to the couple at the time claimed that Kimberly was invited but had a speaking engagement that evening.
