Kimberly Guilfoyle shares glam sexy photos days after fiancé Donald Trump Jr. was snapped hanging out with almost 20-years-younger Palm Beach socialite Bettina Anderson

Kimberly Guilfoyle is flaunting her glitz and glam side as rumors of fiancé Donald Trump Jr's cozy rendezvous with a Palm Beach socialite continue to swirl. 

The former Fox News host, 55, was seen all dolled up in a sexy purple dress in photos shared on her Instagram story just two days after DailyMail.com's story showed Don Jr enjoying an intimate lunch with 18-years-younger Bettina Anderson last month.

Guilfoyle, who has been dating the former president's son since 2018, is yet to comment publicly on the pair's curious lunch date, but shrugged off the rumors in an apparent subtle dig at her beau. 

The former San Francisco prosecutor took to social media to repost a series of glam shots posted originally by friends Cameron Patrick Neth, a jeweler, and fashion designer Oscar Lopez. 

In one video, she is seen seductively blowing a kiss at the camera and showing off her exposed back in the flashy purple gown. 

In another clip she can be seen posing in another, elaborate, embellished yellow dress and twirling around with its attached cape. 

Lopez, the winner Project Runway in 2013 who has previously dressed fellow Trump wife, Lara Trump, showed his support for Guilfoyle in the caption, writing: 'Sexy 4 Ever....#bossbabe #strong #unique #wife #mom.' 

Later on Tuesday, she continued with her regular campaign posts, sharing photos of her and Don Jr.'s recent appearance in Kentucky over the weekend, but remains tight lipped on his rumored dalliance. 

Earlier, DailyMail.com reported that Bettina Anderson was seen in new video schmoozing with the former president's son and his ex-wife their daughter - with Kimberly nowhere in sight. 

Friends told DailyMail.com on Monday that Kimberly had been 'blindsided' by the photos of her beau with another woman, but admitted that she had turned a blind eye to rumors and whispers about her fiancé's alleged wandering eye. 

The insider said: 'Kimberly either didn't know about Bettina – or didn't want to know. Did she hear whispers that Don Jr. was fooling around with someone else? Probably.

'She's no fool but it's easy to deceive yourself when you're so committed to someone and believe he's committed to you.' 

Sources told DailyMail.com that Don Jr's dalliance with Anderson is an open secret in the ritzy Florida town and they have been spotted enjoying each other's company frequently.

That includes the lunch where DailyMail.com's photos were taken with the pair seen kissing several times during the meal at The Honor Bar which sits inside the upscale Royal Poinciana Plaza shopping center.

The source added: 'Don Jr. is not one to account for what he does – not to Kimberly or anyone – except maybe his father. 

'He's pretty bold and, as smart as she is, Kimberly looked the other way.'

Despite Don Jr.'s apparent openness about his association with Anderson, the insider says this doesn't necessarily spell the end of his engagement to Guilfoyle. 

The friend told DailyMail.com: 'What happens now is anyone's guess. Will she stick? Will he dump her?

'She has been so entrenched in the campaign it would look bad to humiliate her. But you could see the writing on the wall at the convention.

'Sure, she was given a platform but the vibrations in the former president's box were not good ones between her and Don. She seemed odd woman out.'

The couple first got together in 2018, three months after Don Jr's ex-wife Vanessa filed to divorce the dad-of-five.

At 55, the San Francisco-born former prosecutor is nine years older than Don Jr, 46, had has previously been married twice.

Her first marriage to Newsom collapsed in 2005 after he cheated on her with Ruby Rippey-Tourk, the wife of his then-campaign manager and former deputy chief of staff, Alex Tourk.

Three months after her divorce from Newsom was finalized in February 2006, Guilfoyle married again – this time to furniture heir Eric Villency.

Their son Ronan was born in October that same year but the marriage was to prove short-lived with the couple divorcing in November 2009.

Since becoming an item with Don Jr, Guilfoyle has become an increasingly high-profile member of the Trump campaign – with the mom-of-one frequently delivering speeches at his rallies and appearances.

Until now, the pair had appeared loved up with Don Jr gushing over their six-year anniversary in an Instagram post four months ago. 

He wrote: 'Happy 6 year anniversary @kimberlyguilfoyle thanks for always being there no matter what the haters are throwing our way. I love you.'

Guilfoyle responded: 'You are my best friend and my soulmate. Here's to us and out incredibly blessed life we share together. Looking forward to creating new memories and enjoying more adventures together.'
