red carpet Paris Hilton 5th Annual Rock The Kashbah virgin unite

Just hours after stepping off a 17 hour flight from Bali, Paris Hilton hit the red carpet for the 5th Annual Rock The Kashbah bash at Boulevard 3, and she looked absolutely amazing in a long black dress.

The event benefitted the Virgin Unite and The Eve Branson Foundation, and P tweeted, "At #RocKTheKasbaH @RichardBranson's charity event Virgin Unite & The Eve Branson Foundation. Such a great cause, love being here to support ... @RichardBranson is such an inspiration as both a businessman and philanthropist. I really admire and look up to him."

P's aunt Kyle Richards was also at the event -- check out the gallery below for more pics!
