In the new issue, on stands Friday, Us Weekly catches up with the cast of the popular 2006-2010 MTV show The Hills to find out where they are now.
Cavallari, 25, welcomed her first child, son Camden, with her fiance, Chicago Bears quarterback Jay Cutler, 29, on August 8.
One person not sending her congratulations: Conrad. Though the two briefly reconciled, Conrad, 26, tells Us, "I don't talk to Kristin anymore."
Another former costar not speaking to Conrad? Audrina Patridge."I don't really talk to Lauren or see her at all," Patridge, 27, revealed to Celebuzz last week. "I think there was a little bit of a falling out. We kind of went our separate ways. The show brought us together and without that show, we all kind of go back to our own thing."
But Patridge did say that she'd reunited with former cast members on the small screen somebody. "Give it another year or two years, because then everyone will be established," she said. "I feel like between two years ago and now, everyone is transitioning and figuring it out."
Pick up then new issue of Us Weekly, on stands Friday, to catch up on all your favorite Hills stars.
