LAS VEGAS, Nev. -- Caption Brad Pitt is all smiles at the press conference for Moneyball in Tokyo on November 9, 2011 Las Vegas was full of stars over the weekend with the Kardashian clan, Britney Spears and Brangelina & their brood all showing up in Sin City.

The acting powerhouse couple and their six children celebrated Brads 48th birthday over the weekend at Cirque Du Soleils Michael Jackson: The Immortal World Tour at Mandalay Bay, according to multiple reports.

They had great seats, sitting right beside the stage, a source told People. They really seemed to enjoy the show. The performers didnt know they were there and a few of them recognized them while they were on stage, so it was pretty exciting.

Another source told The Las Vegas Sun that the family, who was staying at the Four Seasons, skipped out on the limousine ride between their hotel and the show and made the five-minute walk between the two hotels flanked by multiple body guards.

They enjoyed the performance and stayed until the very end rather than sneaking out at the curtain close. They joined the crowd during the final standing ovation. It didnt look as if the cast knew the Hollywood couple was there until they heard the buzz in the audience, another source told the paper.

Adding, It hadnt been announced to them beforehand, so they gave a little nod and a bow in their direction at the end. Brad and Angelina were applauding and smiling ear to ear with their children, who l! oved the show. Then they quietly left to walk back to the Four Seasons.

The Moneyball star turned 48 on Sunday.
