Kid Cudi wasn’t very genteel at GQ’s Gentlemen’s Ball (PHOTOS) at the Edison Ballroom the other night. During his performance, the rapper asked a partygoer what color her lady parts were — he used a different word — prompting the woman to respond, “Pink.” Also there were Ashton Kutcher, who tore up the dance floor with Demi Moore during Akon‘s cover of Michael Jackson’s “Wanna be Startin’ Somethin,” Josh Lucas, and sweatpants-wearing Mark Wahlberg.
