"I hear Stephanie Pratt is sort of stirring the pot," Kristin said.
Kristin Cavallari has some thoughts about Mischa Barton being cast in "The Hills: New Beginnings."
The former "Hills" and "Laguna Beach" star stopped by "Watch What Happens Live with Andy Cohen" Wednesday night, where a caller asked her how she really felt about Mischa joining MTV's reboot of "The Hills," which ran for six seasons from 2006 to 2010.

What's interesting about the casting choice is that Mischa starred in "The O.C.," which inspired MTV to create "Laguna Beach," which led to "The Hills." Kristin said she found it "interesting," too.
"I was very surprised by that!" Andy added.
"Yeah. I was, too," Kristin replied. "I mean, I'm curious like everybody else is to see it. I can't wait."
Kristin -- who stars in her own TV series, "Very Cavallari," with NFL husband Jay Cutler -- said she thinks Mischa will have the hardest time getting along with Stephanie Pratt.
"I hear Stephanie Pratt is sort of stirring the pot," Kristin noted, adding that she still keeps in touch with Audrina Patridge, Heidi Montag and Brody Jenner "a little bit."
Kristin also weighed in on the recent comments Whitney Port made about the cast's infamous trip to Paris that "never actually happened."
"This is the first I'm hearing about this," Kristin admitted. "That was pre-my time, so I've never heard that, but I can tell you most of my stuff wasn't real."
"I'm just happy that more people are coming out and saying that stuff isn't real because, for the longest time, it was only me," she added. "So thank you, Whitney!"
"The Hills: New Beginnings" premieres June 24 on MTV and will star Brandon Thomas Lee and Mischa Barton along with original cast members Audrina Patridge, Brody Jenner, Justin Bobby and Speidi Pratt.
