Foe Kristin Cavallari Hits Lauren Conrad’s Fashion Show

Friends and frenemies turned out for Lauren Conrad's first-ever fashion show Tuesday. Ex-fling Brody Jenner and ex-foe Kristin Cavallari sat alongside Lauren, Lo Bosworth, Audrina Patridge and Frankie Delgado in the front row as the Hills star, 22, presented her collection during L.A. Fashion Week.

Me and Lauren have been cool for a long time, and I'm really proud of her and wanted to support her today," said Cavallari, 21, who clashed with Conrad during their Laguna Beach days after both romanced Stephen Colletti. Conrad's on-and-off beau Jenner who began dating a girl two days after Conrad left for Paris, according to a new Hills clip, told Us he thought her show was amazing. "Everything's going good," he replied when asked how his relationship with Conrad was. Of course, Conrad's show wouldn't be complete without her BFFs (and new roommates) Bosworth and Patridge. (Former Teen Vogue colleague Whitney Port and actress Lisa Rinna, as well as Conrade's family, were also on hand.)

"I'm so excited for Lauren today!" Bosworth, who wore pieces from Conrad's collection to the show, told Us. "It's such a culmination of everything she's been working so hard on for the past few years." Life in their new home is "really good," Bosworth added. "We have a brand new puppy, it's been great. We love it!"

After the show, Conrad got a standing ovation and was presented with flowers.
