Amber Rose made a curious request at the Cinema Society/Brooks Brothers after-party for “Me and Orson Welles” at the Gramercy Park Hotel the other night. The bombshell, pouring out of a thigh-baring pink dress, peeked out from behind the bathroom door to ask a random female partygoer to come zip up the back of her frock. “I have a hard time staying in this thing,” Rose joked to our spy. “But Kanye loves it,” referring to boyfriend Kanye West, with whom she’d just returned from Rome.
