Paris and Nicky Hilton: Playboy Mansion Halloween Party!
With Paris choosing to wear a sexy indian girl outfit and Nicky looking cute in a Superwoman costume, the hotel heiress sisters joined pal Brandon Davis who sported a wacky wig and an orange jumpsuit.
Almost losing her headdress and top during the course of the night, an excited Paris tweeted to her many fans and followers, "Just went into The Haunted House at The Playboy Mansion. So scary and fun!!!"
Making for quite the busy weekend, the former "Simple Life" star spent the previous night hosting her own costume party with guests including her parents, Rick and Kathy Hilton, as well as boyfriend Cy Waits, Adrien Brody, Kim Porter and Perla Ferrar.
