'CSI' Star, Mischa, Paris and more

(Mar. 1, 1:15PM ET) -- TMZ's Josh Levine hit the hottest Hollywood hotspot last night. The Roosevelt Hotel was filled with celebrities. Mischa Barton was front and center with Cisco, as Paris hung with a gal pal. Farnsworth Bentley -- a Diddy peep -- gave Josh the lowdown on his new CD. 'CSI's' Gary Dourdan caused quite the stir. Maroon 5's Adam Levine was there with a new girl -- not Jessica Simpson. And there's a lot more. Check out TMZ's Star Catcher video
