Lauren Conrad couldn’t help but feeling “so nervous!” before her already-successful eponymous line’s show as part of Spring 2009 Mercedes Benz LA Fashion Week at Smashbox Studios last night. Clad in one of her own flowing black maxidresses with perfectly coiffed hair by the backstage team from Warren-Tricomi Los Angeles, the Hills star told PEOPLE that this show is “really girly and fun. I just wanted to have fun with it.” But, the star still took out time for charity. “This show is sponsored by mark and specifically the m.powerment campaign. All the models [are] actually wearing the Have a Heart necklace that we did, and we’re giving $250,000 to seven different foundations, and what’s really cool is they brought some of the girls here from some of the foundations. That’s what it’s all about.” Also in the audience, BFF Lo Bosworth and rumored Conrad amour Kyle Howard, who told PEOPLE he’s “super excited” for Lauren. And even though Whitney Port couldn’t make it, her support came through earlier in the day. “Whitney wrote me a really long message this morning that was the sweetest thing. I mean we’re just really supportive of each other.” says Conrad. See highlights of Lauren’s collection in our video.[brightcoveplayer 1858976138]
