Brad Pitt celebrates 48th birthday in Las Vegas

Brad and his partner Angelina Jolie took their brood of six to Las Vegas on Saturday night to attend the Cirque de Soleil show dedicated to Michael Jackson, whose fan Pitt has been for a long time.

“They had great seats, sitting right beside the stage,” a source told People. “They really seemed to enjoy the show. The performers didn’t know they were there and a few of them recognized them while they were on stage, so it was pretty exciting.”

Recently, the Moneyball star revealed that he plans to quit acting once he turns 50. However, during a press conference in Seoul, he explained that doesn’t mean he will give up working in showbiz all together.

“I wasn’t actually putting an exact deadline on my expiration date [in Australia's 60 Minutes interview], but I see it coming,” Pitt said. “I just have other interests and I do quite enjoy the production side.”

2011 has proved to be a busy year for Brad, whether he was filming upcoming apocalyptic movies, scoring awards nominations, denying marriage and baby rumors or making headlines for his comments on his marriage to Jennifer Aniston.
