Kristin Cavallari, 37, and toy boy Mark Estes, 24, hold hands during dinner ... trends now

Kristin Cavallari, 37, held hands with her TikTok toy boy Mark Estes, 24, as they were seen out together for the first time during a glamorous dinner date in Beverly Hills. 

She went public with her age-gap romance last month, posting a picture of her and Mark cuddled up together during a getaway to Los Cabos.

Their sizzling new relationship was still going strong when they were glimpsed Friday night ambling cheerfully down the street after emerging from a restaurant.

Mark, a model and social media personality, wore a t-shirt and shorts that bared his toned and bronzed arms, as well as his sprawl of tattoos.

The smoldering heartthrob flashed his tantalizingly rakish smile as he headed up the sidewalk with his reality star girlfriend grasping his hand.

Kristin, who shot to fame on The Hills before starring on her own show Very Cavallari, was the image of Beverly Hills chic on her latest date.

She played up her vertiginous legs in a pair of skintight black leather trousers and pulled on a white top that clung to her petite torso.

Alongside his modeling career, Mark is part of a TikTok collective called Montana Boyz, which currently boasts over 465,000 followers.

He himself hails from Montana, where he played wide receiver for Montana State University's football team, but now lives in Nashville, where Kristin is also based.

Kristin debuted their romance on Instagram with a tableside selfie in Los Cabos last month, writing: 'He makes me happy.'

A source then spilled to TMZ that Kristin and Mark were seen indulging in a public display of affection on their flight to Los Cabos. 

Insiders explained that Kristin and Mark had only been seeing each other for about a month and were not yet in a serious relationship.

On a new episode of her podcast Let's Be Honest, Kristin giddily remembered feeling like a teenager during her first date with Mark.
