Jamie Foxx, partying until closing time at Pearl, a restaurant and champagne lounge at Miami club Nikki Beach. The Dreamgirls star ordered two bottles of Dom Perignon champagne, Belvedere vodka and Patrón tequila. And when the munchies struck at 4 a.m., Foxx and his posse ordered a large cheese pizza. The crew left an hour later – but not before thanking the staff, a source tells us.
