Angelina Jolie & Family: Las Vegas Fun!

Power couple Angelina Jolie and Brad Pitt were snapped taking their children Maddox, 10, Pax, 8, Zahara, 6, Shiloh, 5, and 3-year-old twins Knox and Vivienne to to see Cirque du Soleil's Michael Jackson THE IMMORTAL World Tour in Las Vegas, Nevada on Friday (December 16).

Angelina held Zahara - who wore an adorable sea shell patterned dress under a tan trench coat - by the hand as they walked behind security through the Mandalay Bay Hotel after the performance. Brad - who turned 48 on Sunday - held sweet Shiloh's hand while big brother Pax trailed behind the famous group.

"They enjoyed the performance and stayed until the very end rather than sneaking out at the curtain close," an eyewitness reveals to the Las Vegas Sun's Robin Leach. "They joined the crowd during the final standing ovation. It didn’t look as if the cast knew the Hollywood couple was there until they heard the buzz in the audience."

“It hadn’t been announced to them beforehand, so they gave a little nod and a bow in their direction at the end," the source continues. "Brad and Angelina were applauding and smiling ear to ear with their children, who loved the show. Then they quietly left to walk back to the Four Seasons.”

Happy 48th Birthday Brad!
