Benny Medina - Nicole Richie's manager, among others - sure knows how to entertain! The Hilton sisters, along with gal pal Kimberly Stewart (whose posh hair has been that way for a while, folks!), started off their Friday evening at Villa off Melrose before heading over to Benny's big bash. And check out who else attended below!


Ashley Olsen, who didn't want to be seen - maybe because the controversy surrounding her sis?


Guess Mischa's back from Sundance finally!

And it looks like she was so excited to be out of the cold weather that she decided to go braless! Cover up, Mischa - especially when you're wearing a see-through top!
