Jamie Foxx had a surprise serenade from THE BLACK EYES PEAS star Fergie on Thursday (14DEC06) as he enjoyed a boozy birthday bash in Las Vegas. The Oscar winner, who turned 39 the day before (13DEC06), was presented with a sparkler-topped birthday cake by the singer, before she led the crowd at celebrity hangout Jet in a rendition of HAPPY BIRTHDAY. After moving the party on to Tao, Foxx joined Fergie and her bandmate WILL.I.AM performing on stage. As well as toasting his birthday, the singer/actor was also celebrating four Grammy nominations earlier this month (07DEC06).
