Turn up the Hilary Duff music, ladies. Kristin Cavallari is coming clean…about her relationship with Lauren Conrad. On July 11, the now 31-year-old appeared on Andy Cohen’s Watch What Happens Live alongside RHONY star, Sonja Morgan.

While we thoroughly enjoyed Kristin’s commentary on Bravo reality TV, we were much more interested in a segment called "Spill The Hills Tea." Kristin opened up about her current correspondence (or lack thereof) with former cast members of The Hills and Laguna Beach, especially her longtime rival, LC!

"Now that you’re both mothers, could you see you and Lauren swapping tips and tricks?" Andy Cohen asked the mother-of-three. "Probably not, there’s no animosity but we’ve never stayed in touch," Kristin revealed. "Who would have to make the first move?" Andy inquired about the potential for a conversation between the two. "Me," Kristin replied — practically sighing.

Of course, Kristin’s diss pales in comparison to the insults the gals used to hurl at each other back in the day. It might have something to do with the fact that they’re no longer fighting over the same dude. To be fair, though, Stephen Colletti was (and always will be) a bona fide babe — who wouldn't fight over him?

Speaking of Stephen Bae-letti, Kristin also revealed to Andy Cohen that she still talks to her former flame. In fact, she’s even thinking about asking him to make a cameo on Season 2 her new reality series, Very Cavallari. That said, her series has yet to be picked up for another go-around. Here’s hoping it does — for the soul purpose of getting to see the high school sweethearts interact once more!
