Donald Trump Jr. is seen flaunting his romance with socialite Bettina Anderson in Palm Beach…with no signal of fiancée Kimberly Guilfoyle

Hand in hand, Donald Trump Jr. and his new socialite love Bettina Anderson enjoyed a romantic night out at an exclusive Palm Beach eatery as part of her lavish birthday celebrations, exclusive DailyMail.com photos reveal. 

The pictures are incontrovertible proof the soon-to-be First Son has moved on from fiancée Kimberly Guilfoyle to be with the stunning ‘it girl’ – a pillar of top-drawer society in the Florida billionaires’ enclave who Don calls ‘perfect’.

The loved-up couple spent nearly two hours at swanky downtown hotspot Buccan, three miles from her West Palm Beach townhouse where they have been spending days and nights, we can reveal.

The high-end bistro is billed as a ‘hip upscale casual café’, where dishes include seared snapper for $39, Iberian Duroc Pork for $52, and Japanese Wagyu Ribeye for $125.

Don Jr., 46, 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 – wearing loose and flowing black pants with a black vest-like top and clutching a maroon purse with a gold clasp – stayed close to her man as they approached his pickup truck parked directly opposite the restaurant, their fingers interlocked.

She was also sporting what appeared to be a large man’s gold Rolex Datejust watch, typically costing around $15,000.

The President-elect’s eldest son chivalrously opened the passenger door for her and guided her inside. He then closed the door gently before moving around the back of his vehicle, getting in and firing it up. 

Our stunning photos come just three months after DailyMail.com exclusively revealed the pair were canoodling at another Palm Beach restaurant during a lunchtime assignation, locking lips in front of incredulous diners.

It was the first time the newly minted couple were revealed to be consorting.

Donald Jr. continued to be photographed with 55-year-old Guilfoyle after our revelation, but she has not been snapped with him since November 12 – and was reported to have been ‘blindsided’ by the contents of our original story.

The now former couple got engaged in December 2020 and bought a $15.5million waterfront mansion together in an ultra-secure development in Jupiter, Florida, four months later.

However, DailyMail.com can exclusively reveal 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. 

It was also on the day she posted a social media picture of birthday flowers, referencing @donaldtrumpjr. 

The next president’s son stayed overnight with Anderson on Friday through Saturday after she enjoyed a magnificent birthday dinner that included a bottle of 2013 vintage Salon champagne, which typically costs an eye-watering $1,300.

She posted a social media image of the super-expensive fizz being poured by a waiter, writing ‘S is for Spoiled’. 

And in a clear reference to her new beau, she added: ‘How sweet it is to be loved by you’, accompanied by the the James Taylor song. In a further message, she wrote: ‘IYKYK’, meaning, ‘if you know, you know.’

Don Jr sent his new love a card saying ‘I think you’re perfect’ to mark her 38th birthday.

There was also a photo of a birthday cake being presented to her at the table, with a man who appears to be Don Jr., in a jacket and open necked white shirt, next to her taking a picture on his phone. 

Posted on Saturday, Anderson cryptically captioned it: ‘Definitely feeling a year (or 2) older after last night’.

But the piece de resistance of the celebration was undoubtedly an astonishing 19 inch Y-shaped diamond necklace in 18 carat white gold and with more than 100 jewels weighing a total of 28.27 carats.

The model, influencer and philanthropist from a family with impeccable Palm Beach credentials was wearing it at the dinner on Friday night, setting off her red, blue and black outfit.

Hours earlier she posted a photo of the dazzling piece, along with diamond earrings and the tantalizing words: ‘Tonight I’m gonna have myself a real good time’, accompanied by the sounds of Queen’s hit, Don’t Stop Me Now.

She added ‘I feel alive’ and ‘birthday baubles’, plus the name of Palm Beach’s Hamilton Jewelers, situated on the ritzy town’s exclusive shopping street of Worth Avenue.

There’s no price tag on Hamilton’s website for the necklace and it is not known if Anderson was loaned it for the evening or had it bought for her. But similar necklaces fetch well over $100,000.

The store describes it, saying: ‘This exquisite 18k white gold diamond ‘Y’ necklace features a stunning combination of one pear-shaped diamond and multiple round brilliant cut diamonds, graduating in size.

‘With a total weight of 28.27 cts the diamonds are graded E in color and S11-S12 in clarity, offering exceptional brilliance and fire… a truly elegant piece that captures timeless beauty and unmatched craftsmanship.’

Donald Jr. left Anderson’s home on Saturday morning after the big night out in his pick-up truck, but returned around lunchtime to collect her.

And in a sign of family acceptance of the relationship, he drove her to the exclusive compound to continue celebrations with a special balloon-themed birthday cake – courtesy of his ex-wife Vanessa, we can reveal. 

Although President-elect Trump wasn’t there due to his trip to France for the reopening of fire-ravaged Notre Dame cathedral in Paris.

Pictured on an outside glass table, the cake was adorned with 10 candles. Anderson posted it with the caption: ‘Thank you@officialvanessatrump.’ It is understood the women have been friends for many years.

Mid-afternoon the pair headed back to Anderson’s home in Don Jr’s truck. Bettina later went out on her own, glammed up in a short black dress and high heels to be at the center of a children’s charity event in the swanky Royal Poinciana Plaza shopping venue.

She posed for photos with fashion designer Stacey Bendet, 46, and Kathy Hilton, the 65-year-old designer and actress mom of celebrity Paris, 43, before driving home after about an hour.

Meanwhile, Don Jr left her house to speak at the 2024 Turning Point USA gala at Mar-a-Lago. The organization is a non-profit that advocates for conservative politics on high school and college campuses.

He started the weekend with his new flame by arriving at Anderson’s pad on Friday afternoon.

They nipped out to a local bakery, as revealed in exclusive DailyMail.com pictures, before heading back before the big night out.

The birthday girl’s charity event a day later was just feet away from the Honor Bar where she and Don Jr. were spotted canoodling at a table on August 17 during an intimate lunch date, as exclusively revealed by DailyMail.com.

Three times Anderson leaned over to plant a kiss on her new man’s lips and at one point reached down below the table, put her hand on his thigh and rubbed it.

Born in Palm Beach with a twin sister, Anderson’s late father was Harry Loy Anderson who became the youngest bank president in the country when he took the helm of Worth Avenue National Bank at the age of 26. 

Mother Inger, 74, still lives in an $11.5million home in an exclusive section of the mega-rich enclave.

Statuesque Bettina co-founded The Paradise Fund with her two brothers in 2005. 

She attended Palm Beach Day School followed by St Andrews School in nearby Boca Raton where fees range from $30,885 a year for lower school to $72,420 for the most senior boarders.

Next it was a BA in Art History, Criticism and Conservation from Columbia in New York City, where she lived for a further three years before returning home and starting her ascent to become an essential part of Palm Beach’s exclusive social circuit.

Her social media is crammed with glamorous professional modeling shots and vignettes of her life – including spearfishing in the Bahamas where she claims to be the happiest.

Her profile with online designer store Moda Operandi – which features her modeling outfits – gushes: ‘Her style, like her personality, blends flirty femininity with a spicy sense of humor and embraces a broad range of brands.

‘Whether she’s headed out for a night in a show-stopping Oscar de la Renta mini, sporting a Zimmerman one-piece poolside, or hosting at home in a matching set from Cult Gaia, she’s a walking paragon of style.

‘She’s also the perennial ‘life of the party’ defying Palm Beach stereotypes and rewriting the rules of womanhood along the way.’

Her style tip was ‘knowing your body and having confidence in whatever you wear’. And she revealed: ‘I love creating intimate and memorable experiences with friends.’

A profile in the local edition of Avenue Magazine says simply: ‘Every town has an ‘It’ girl and in Palm Beach it’s Anderson.’
