Enrique Iglesias premiered his new single, “Turn Up the Night,” for 100 close friends Tuesday at the General’s subterranean Jazz Room. The sexy singer was spotted working the room and exciting female fans. “They were all giggling and yelped when he headed their way,” said a spy. “He was giving people hugs.” Iglesias was joined by Republic Records’ Charlie Walk at the party, which we’re told ended next door at nightclub Finale. We hear the song will debut later this month.
