Lauren Conrad spent her Saturday night clowning around in LA with Lo Bosworth and their friends at the Playhouse club. LC went with bright red lips and a short black dress for her evening of fun, as she took a break from working on the layout for her upcoming guide to style. That's just the latest project in Lauren's busy post-Hills life, and there's still lots more coming our way. She's hard at work on her follow-up to LA Candy and is working on adapting her first novel for the big screen.
