Kristin Cavallari, 37, says she has the “best sex ever” with her boyfriend Mark Estes, 24.

Things are heating up between Kristin Cavallari and her boyfriend Mark Estes.

The 37-year-old “Very Cavallari” alum confessed during this week’s episode of her “Let’s Be Honest” podcast that her current relationship with the 24-year-old influencer has given her the “best sex” she’s ever had.

Estes joined Cavallari for a game of “Truth or Drink,” during which they talked about their satisfying chemistry in the bedroom and how sex has gotten better for them with age.

“I think it’s a lot of things. I think sex for women gets better as they get older,” the Uncommon Gems founder shared, according to Us Weekly .

“Because I think women, when you’re in your 20s, you’re insecure in a lot of ways, you’re worried about your body or something. [you] Look-alike.”

She added, “I’ve let go of that and I feel like I’m more physically present during sex than I ever have been. And I’m so much more attracted to you. And I think we have really hot sex.”

Estes surprised the former “Laguna Beach” star by telling her that it was definitely the “best sex” he’s ever had.

“I didn’t really know that,” she replied. “You never said that to me. We’ve talked about how great our sex is, but you’ve never outright said, ‘You’re the best.’ I would have remembered that.”

Elsewhere in the episode, released Tuesday, the couple discussed their sexual fantasies and whether or not they had ever faked an orgasm.

The mother of three has previously opened up about her relationship with her younger boyfriend.

In April, Cavallari revealed that things were getting “pretty serious” between the two as they discussed the possibility of having a baby.

“One of the things that — I’m not actively thinking about it, but it’s definitely on my mind — is that, you know, he wants a baby,” Cavallari said on her podcast. “So, you know, I’m considering it.”

The “Hills” alum is mom to sons Camden, 11, and Jaxon, 9, and daughter Saylor, 8, whom she shares with ex-husband Jay Cutler.
