Kristin Cavallari, 37, proudly shows off her shirtless boyfriend Mark Estes, 24, in gym selfie as they work up a sweat together - after admitting 13-year-age gap was a 'hang up'
Kristin Cavallari flaunted her hunky boyfriend Mark Estes in a sexy gym selfie on Wednesday.
The Laguna Beach star, 37, showcased her own fit figure in skintight workout gear as she stood beside her shirtless boyfriend, 24, and flashed a wide grin.
She swooned over her beau's ripped physique as she captioned the photo: 'He's hot.'
In the photo, the TikTok star, who is a member of the Montana Boyz, showed off his tattoos and muscles as he sported just a pair of black basketball shorts and white sneakers.
The reality TV personality — who has been posting more photos of them together as their age-gap romance gets serious — was seen wearing a plunging sports bra and high-rise leggings.

In the snap, she looked barefaced and fresh as she opted out of any makeup and threw up her blonde hair into a messy topknot.
On the same day, she also posted glamorous photos of herself done up to promote the new Beachside Collection for her jewelry brand Uncommon James.
The fashion designer showcased her toned abs as she modeled a black bikini top with ruffles and jean shorts in a post she captioned: 'Seashells, baby blues, colorful beads, and starfish all summer long.'
Her long hair was styled in summery beach waves with a white headband scarf she wore as a headband.
The Hills alum accessorized with a thick jute belt and chunky, aqua blue hoop earrings.
She also layered several necklaces with dainty starfish pendants and beaded chains as well as similar, gold bracelets.
She previously teased the pinup shots last week when she was working on the shoot in a tropical location as she celebrated the seven-year anniversary of her founding her jewelry brand.
Her new posts come as her romance with Estes heats up and a source from her inner circle told Us Weekly in March that the couple have a 'genuine connection.'

About the people in Cavallari's inner circle, the insider said: 'After seeing them together, they realize Kristin and Mark have a genuine connection, and they see how happy he makes her.'
Last month, the television personality also opened up about wanting to have a baby with him.
She shares three children with her ex-husband Jay Cutler — with whom she was married from 2013 to 2022.
Cavallari and the former football quarterback share sons Camden, 11, and Jaxon, nine, as well as daughter Saylor, eight.
Earlier this year, she made their relationship with Estes Instagram official when she shared a photo of them vacationing in Los Cabos, Mexico together.
The day before their trip that February, she admitted she was hesitant about their 13-year age gap at the beginning.
'I recently started dating someone, and I was a little hung up because there's an age gap,' she said during an episode of her podcast Let's Be Honest with Kristin Cavallari.
'I will say there's an age gap with us, which is my big hang-up on it,' she continued. 'Listen, age is a number. I'm insanely attracted to him. He's so perfect. The only thing is he's younger than me, like, a lot younger.'

In March, she also revealed they met on social media and recalled how their romance kicked off during another podcast episode.
She later admitted that she thought Estes, who she called 'the hottest man I've ever seen,' would just be a 'f*** buddy.'
'When I first met him I didn't think it was going to turn into what it's turned into,' she admitted on her podcast.
'He's the hottest man I've ever seen, so I was like, "Perfect, I'll make him my f**k buddy."
'Because I didn't have one. I really haven't had one here in the four years that I've been divorced. Guys, the lack of sex in my life is real.'
She also added that although it was 'too soon to tell' if she would have kids with Estes, he had changed her mind about more children as she previously thought she was 'done.'
'Everyone else I've gone out with it's like, "No, I'm not having any more kids." But you meet the right person and it can change that.'
