Last night Ashlee Simpson attended the launch preview of black 15in1 at the Andy Lecompte Salon in Los Angeles, and the skinny starlet mingled with stars like Odette Yustman, Jessica Stroup, Mena Suvari, Taryn Manning and Vanessa Minnillo. Wait, Vanessa Minnillo?! Think the event coordinators had to keep these two away from each other? After the snide yet hilarious comments Jessica Simpson made about Nick Lachey's lady love, we can't imagine her sister is a fan!

After the event was over, Ashlee met up with hubby Pete Wentz for dinner at Beso, but we're not sure whether she actually ate anything...
