Donald Trump Jr. and Kimberly Guilfoyle have reportedly split up.

And the son of U.S. President-Elect Donald Trump appears to have already moved on with his life after being photographed alongside his new squeeze, a Palm Beach socialite.

“Don and Kimberly haven’t been getting along over the past year,” a source told the New York Post‘s Page Six. “They get argumentative at Mar-a-Lago in front of people. Nothing crazy, but you know when a couple is fighting. They bicker in public.”

The report also suggests the pair’s relationship was rumoured to have been on the rocks for months while two other sources said they had officially gone their separate ways.

On Tuesday, Britain’s Daily Mail published images of Don Jr. holding hands with Palm Beach socialite Bettina Anderson following a romantic night out Monday at an exclusive eatery.

“Bettina and Don have been together for a few months, and are super cute and happy together,” another source told Page Six. “It’s just a natural fit — everyone is happy for them!”

The report also detailed a lavish weekend to celebrate Anderson’s 38th birthday, with Don Jr. gifting her a diamond necklace in white gold that included 100 jewels.

On Wednesday, around the same time Page Six reported the couple’s split, President-elect Donald Trump named Guilfoyle as U.S. ambassador to Greece.

“For many years, Kimberly has been a close friend and ally,” Trump wrote on Truth Social. “Her extensive experience and leadership in law, media, and politics along with her sharp intellect make her supremely qualified to represent the United States, and safeguard its interests abroad.”

Following the ambassadorship announcement, Don Jr. posted to social media that he supported Guilfoyle’s appointment.

“I am so proud of Kimberly,” he wrote on his X account. “She loves America and she always has wanted to serve the country as an Ambassador. She will be an amazing leader for America First.”

Around the same time, Guilfoyle wrote that she was honoured to be selected for the post.

“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,” she wrote on X.

Neither Don Jr. nor Guilfoyle have publicly commented about their reported split.
