Kristin Cavallari is dating Mark Estes

The 37-year-old TV star revealed in February that she's dating Mark Estes, and Audrina has admitted to being thrilled for her showbiz pal.

The 38-year-old star told Us Weekly: "I had to text her … She was like, ‘Oh, thank you so much'. And I’m just happy for her. She deserves to be happy."

Audrina was initially shocked by the news - but she also thinks that Kristin deserves to "have some fun".

She said: "At first I was like, ‘Is this real? Or is that a publicity stunt?'

"They’re actually really cute together. Maybe she needs to have some fun in her life."

Mark is actually 13 years younger than the reality TV star. However, Audrina doesn't think it's a big issue at all.

She explained: "Kristin is the last person that ever would [care]. She is going to live her life as she should."

Kristin and Jay Cutler finalised their divorce in 2022, and the blonde beauty recently revealed that she remains on good terms with her ex-husband.

Kristin - who has Camden, 11, Jaxon, nine, and Saylor, eight, with Jay - said on the 'Let's Be Honest with Kristin Cavallari' podcast: "I never thought we would get here. I never thought we would get here. I didn’t. I’m so happy about it.

"Oh my god. I’m so happy about it because, you know, everyone wins when parents are on good terms."

Kristin and Jay are determined to make their children their number one priority.

She said: "My kids see it, I mean, it’s just easier. And listen, I get it. When people’s hearts are breaking, it’s really difficult. It’s really, really difficult, and so, you know, seeing Jay happy is the best.

"That’s what I care about because I obviously see the benefits, my kids see the benefits, and yeah, life is really good right now, and I’m so thankful for it."
