Kristin Cavallari and Heidi Montag Just Had a Mini Hills Reunion

We finally got a Hills reunion… well, sort of. Mom-to-be Heidi Montag took some time out to see former co-star Kristin Cavallari while the latter was in LA this week!

Both ladies shared a photo from the meet-up on their Instagrams, with Kristin writing, “This girl. Love her and that cute little belly. Thanks for coming by @heidipratt,” while Heidi said, “So much fun catching up with @kristincavallari!” See the adorable pic in the video below.

Kristin revealed she’s down to get the rest of the girls back together seven years after the MTV series went off the air. “Well, I would love to do a Hills reunion with the moms,” the 30-year-old admitted to E! News. “I wouldn’t want to bring my kids, necessarily, because I don’t put my kids out there like that, but I’m totally open to a reunion. I would love to see everybody.”

The reality show premiered in May 2006 with Laguna Beach alum Lauren Conrad at the helm, but Kristin entered the mix in Season 5 when original cast member Whitney Port left to do her own spin-off. Scroll through the gallery below for more info about the recent Hills baby boom (aka every person has a kid now)!

Whitney Port has a son.

Whitney shared her and husband Tim Rosenman's baby news on Instagram in February. "Oh hey!" she wrote. "Just standing by the window in my underwear, with a BABY in my belly!!! DM me if you know what I'm supposed to do with this thing for how ever many years I'm supposed to be in charge." She welcomed Sonny Sanford Rosenman on July 27.

Kristin Cavallari has three kids.

With sons Camden and Jaxon and daughter Saylor, Kristen and her husband Jay Cutler have one of the cutest families we've ever seen. "Every child is completely different. My two boys are opposites. Camden was such an easy baby. Jaxon is more of our rebel wild child, but he's also a mama's boy," Kristin wrote in her book, Balancing in Heels. "Our little girl will have her own personality."
