R+B star and actor Jamie Foxx ended a week of 40th birthday celebrations in Las Vegas on Friday night (21Dec07) with a party at Jet nightclub. Sporting a stylish white pinstriped shirt, black necktie and vest and grey trousers, Foxx partied with guests like Martin Lawrence. The actor/singer started his week-long celebration with a Miami, Florida bash, at which he sported low-riding shorts - and nothing else! Foxx ended his party week with an impressive triple-tiered cake from Jean-Philippe Patisserie and he even treated the crowd to a few songs, including Bob Marley's reggae anthem One Love and his Kanye West collaboration Gold Digger.
