Donald Trump Jr. publicly introduces his new girlfriend Bettina Anderson at Mar-a-Lago following his breakup with Kimberly Guilfoyle

Donald Trump Jr. is openly displaying his new relationship with Bettina Anderson following reports of his breakup with fiancée Kimberly Guilfoyle, according to sources from DailyMail.com.

The president-elect’s eldest son apparently made a public appearance with his new girlfriend at a dinner hosted at his father’s Mar-a-Lago club on Wednesday, where the two were observed ‘showing off their affection for everyone to witness.’

Insiders characterized the couple as ‘deeply in love’ and disclosed that they made no effort to conceal it while ‘engaging in laughter and private conversations while waiting in the buffet line,’ as detailed by Page Six.

At one point they were also seen briefly chatting to Donald Trump just moments before the President-elect left Mar-a-Lago for his trip to New York City. 

Don Jr., 46, and Anderson, 38, had first set tongues wagging when they were snapped getting cozy at brunch in late August – and have all but confirmed their romance since then. 

As DailyMail.com reported at the time, Anderson, a Palm Beach socialite and Republican ‘it girl’, is likely to have run in the same social circles as the Trumps for years and has been previously seen attending events at Mar-a-Lago.

And according to one source: ‘Trump insiders have known about Bettina for months’ and Don has been ‘chomping at the bit to show her off at Mar-a-Lago.’

‘She’s been there before, of course, but he’s been much more discreet about being together. And together they are,’ the insider told DailyMail.com on Friday. 

‘He’s bewitched by Bettina – her looks, her smarts, her pedigree. Now that Kim is out of the picture the relationship is going to get even more serious.’ 

The couple’s dalliance was only publicly confirmed this week by DailyMail.com photos of their intimate dinner date, though locals have reportedly known about it for months.

One insider told DailyMail.com that the two had been ‘seen together all over Palm Beach’ at the time we first revealed their cozy rendezvous at The Honor Bar this summer.

But for the rest of the world speculation reached a fever pitch this week, when they were seen holding hands, going on dates together, and celebrating Bettina’s 38th birthday, in exclusive DailyMail.com photos. 

Anderson also added to the frenzy of speculation by sharing social media photos of her new beau lavishing her with birthday gifts. 

And just two days later, at their Mar-a-Lago dinner date, the pair once again left little doubt about where they stand. 

Anderson, a registered Republican, had previously shown off her ties to the Trump family in a close-up selfie with Donald Jr.’s half-sister Tiffany, 30.

She has also visited Mar-a-Lago, posing for photos in designer clothing. In one shot on her social media, she is snapped outside the resort with her mother. 

In another society shot she’s enjoying a lavish 2023 New Years Eve celebration in a black floor-length dress next to her mom, who is in a glittery black number. The photo is on her Instagram feed in a folder called PB Season ’23.

She also appears to have a friendly relationship with Don Jr.’s kids and his ex-wife Vanessa, with whom she was seen sharing a seat on a patio chair and intimately chatting while drinking bottled beer at a party in September. 

Their Mar-a-Lago date comes within days of DailyMail.com exclusively revealing that Don Jr. and Kimberly Guilfoyle officially called off their engagement three months after she was ‘blindsided’ by photos of her fiancé cozying up to Bettina.

Rumors had continued to swirl since initial reports emerged, but both Don and Kimberly have remained consistently silent on their relationship status.

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

‘Their engagement hasn’t officially been called off yet. They were waiting until after the Inauguration to announce.’

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

As an apparent consolation prize, President-elect Trump earlier this week nominated Guilfoyle as the ambassador to Greece.

The Trump campaign advisor, 55, took to social media shortly after the President-elect’s announcement to say she is ‘ready to serve’, but did not address her split with his son. 

‘She’s putting on a brave front, of course, but she was crushed about Don’s very public betrayal,’ one source told DailyMail.com on Wednesday. 

‘Once Don fell for Bettina the writing was on the wall for Kimberly. The split was  going to happen quietly after the election, but Daily Mail’s photos preempted that. 

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

Despite the photographic evidence and mounting rumors in recent months indicating their split, Guilfoyle had remained on the scene as a faithful Trump campaign advisor in the lead up to the election and was snapped alongside 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 at recent family events further sparked curiosity about the couple’s future.

Don Jr. has also kept mum on their breakup, and in an apparent bid to keep up appearances Tuesday, he publicly congratulated his estranged fiancée in an X post that she then shared on her social media accounts. 

‘I am so proud of Kimberly. She loves America and she always has wanted to serve the country as an Ambassador. She will be an amazing leader for America First,’ he said. 

As DailyMail.com exclusively revealed earlier this week, Donald Jr. now spends nights at Anderson’s relatively modest $860,000 townhome in West Palm Beach.

Her place is only a mile from his father’s sprawling oceanfront Mar-a-Lago Club, set once more to be the Winter White House.

The couple’s lovey-dovey dinner Monday night came after a lavish weekend of celebration for Bettina’s 38th birthday. 

The loved-up couple spent nearly two hours at swanky downtown hotspot Buccan, three miles from her home. 

Don Jr. dressed in a smart blue suit and white shirt open at the neck, revealed no compunction about showing off his new flame as they emerged from the restaurant just before 10pm.

They came out with another couple and Don Jr. could be heard laughing before they bade the others farewell and headed across the street to his vehicle, totally smitten with each other.

Anderson herself also dropped not-so-subtle hints of their romance, sharing photos of a romantic flower delivery on her Instagram story, in which she discreetly tagged her new beau, @donaldtrumpjr on the top left corner. 

The photo showed a note sent with the flower arrangement reading: ‘Many have said you’re aging out but I think you’re perfect…happy birthday!’

Anderson responded to her beau’s message in a tongue-in-cheek caption saying: ‘Tough but fair.’
