Paris Hilton takes Halloween very seriously. Although there have been a lot of stars sharing costume snaps on Instagram, no one posted as much as the former-reality-star-turned-DJ over the weekend. It all started on Friday night, when Paris debuted her Minnie Mouse costume in a series of shots before attending the popular Casamigos party. Come Saturday, she went nude for a snap showcasing a mask. But perhaps the most elaborate costume of them all was unveiled early Sunday following Seth MacFarlane's birthday celebration. Paris donned a sexy Playboy Bunny ensemble for the occasion, keeping with the theme of costumes we've seen her wear in years past.
