Paris Hilton celebrated her 30th birthday party in style last night -- throwing a giant, Moulin Rouge-themed affair!
The 300-person bash took place at a private house in the Hollywood Hills, where the birthday girl showed up with boyfriend Cy Waits dressed up as a can-can girl in a sparkly red corset, a feather skirt, black fishnets and red heels.
Also photographed entering the party in a barely there ensemble was Kathy Griffin -- the 50-year-old showing off her still-amazing body in some short lingerie, booty shorts and boots.
The party must have gone all night, because just moments ago Paris finally Tweeted her thanks out to all the guests who made it, saying "Such an amazing birthday celebration! Moulin Rouge themed fun! Big thanks to my DJ's for the night! So amazing when Lil Wayne stopped by to give me a birthday present. Everyone at the party loved seeing him!"
Paris officially turns 30 tomorrow.
