The girl who started it all, Lauren Conrad. She started off with MTV's Laguna Beach. She's now a best selling author and designer.
Kristin Cavallari was a junior in high school when she taped the first season of Laguna Beach. She clashed with Lauren Conrad as they both vied for Stephen Colletti. She is still stirring up drama: She angered Audrina Patridge when she went after Justin Bobby. "It's fun to play the bitch," Cavallari, 23, tells Us.
During her first season of The Hills in 2006, Audrina Patridge dated Spencer Pratt before romancing Justin Bobby and Australian BMX rider Corey Bohan. The aspiring actress, 24 — who's back on with Bohan and leaving The Hills after the sixth season — has surgery rumors. "I'm just losing my babyfat," she told Extra earlier this year.
When Heidi Montag began The Hills in 2006, she was BFFs with Lauren Conrad. Since then she's had.. some work done. Now, she is BFFs with Spencer Pratt. Downgrade.
Brody Jenner (of the 2005 Fox reality show The Princes of Malibu) joined the cast of The Hills as Spencer's BFF, and romanced most of the women of the show. He now dates rocker, Avril Lavigne. He had this to say of Season 6 of The Hills "Keep an open mind and watch."
Before joining The Hills in 2007, Stephanie Pratt struggled with drugs and later battled bulimia. "I remember saying, 'I can't believe how huge I look walking over to Lauren [Conrad],'" she tells Us. Now healthy and happy, Pratt, 23, has a new outlook on her body: "The more I can stress about being honest, [the better]," she tells Us. "You are as healthy as your secrets."
