When Jay-Z is away, his bootylicious babe Beyoncé will play. Spies at The Box Thursday night saw her and three girlfriends enjoying the club's risque show while flanked by a "huge bodyguard" and protective curtains around their table.

"Beyoncé was really making the most of the burlesque strip show," said the source. "She was on the table in the VIP balcony cheering loudly as two girls got naked and licked each others' feet. She stayed until 3:30 in the morning."
