The 37-year-old mother-of-three - who has sons Camden, 11, and Jaxon, nine, and eight-year-old daughter Saylor, with her ex-husband Jay Cutler - took to TikTok to address the hate she's received for dating a "toy boy".

She captioned the clip: “When they’re all up in arms that I’m dating a 24 year old. Andddd?”

And she lip-synced: “So what are you going to do about it? Are you going to arrest me? Are you going to give me a ticket?”

The couple confirmed their romance last month after they were spotted in Mexico together.

The former 'Laguna Beach' star captioned an Instagram snap of the pair on their romantic getaway to Cabo San Lucas: “He makes me happy," along with a white love heart emoji.

Kristin was married to Jay for seven years before they called it quits in 2020.

The former reality star revealed she was dating again last September.

She told Us Weekly magazine: “I’m dating. I’ve gone through phases of going on a million first dates, and I’ve gone through phases where I’m not dating at all.

“At the moment, it’s not my priority, but I’m open to it.”

Meanwhile, Kristin recently spilled that she was "love-bombed" by Sean 'Diddy' Combs.

She claimed the rapper became enamoured with her 15 years ago during her early days in the television industry and got her telephone number from a mutual friend before showering her with flowers, chocolates, toys and bottles of tequila in a bid to get her to go out with him - but Kristin didn't agree to a date and she now thinks she "dodged a bullet".

During an episode of her 'Let’s Be Honest' podcast, Kristin explained: "I was 22, I believe, we had a mutual friend, he got my number, whatever. He sent me the biggest bouquet of flowers I’ve ever seen. The biggest box of chocolates I’ve ever seen. A huge teddy bear.

"I mean, it was multiple people bringing [stuff] into my house. It was like [stuff] you see in a movie."

Kristin decided against going out on a date with the hip-hop star, 54, but she was tempted.

She added: "I mean, there’s obviously a part where you’re like, ‘Whoa, this guy is spoiling the ... out of me.' Like that’s so sweet, and I’ve never met this guy."

Despite being turned down, Combs didn't give up with Kristin revealing he "kept asking [her] out".

Kristin said: "Now, as an adult, I’m like, ‘Red ... flag!' I mean, that’s some love-bombing kind of [stuff] ... I dodged a ... bullet ...

"I could never just go on a date with someone because it was so-and-so. I have always had to be attracted to you. … I don’t want to be the arm candy."
