Everyone appreciates a good barbecue -- even more when it's Paris Hilton heatin' up the hotdogs!

The sullied socialite had her closest friends over to her pad for a Memorial Day BBQ yesterday, with guests ranging from "Simple Life" co-star and on-again BFF Nicole Richie, to MTV VJ turned D-Lister Simon Rex.

Paris was quiet around cameras when she appeared at her front door for an American flag-hanging photo op, though Rex told photogs the jail-bound blonde is "doing good."

Other guests included Paris' sis Nicky, Brandon "Greasy Bear" Davis, Keisha Cole, director Brett Ratner and Elisha Cuthbert.
