The Jolie-Pitts hit Sin City!
On the eve of Brad Pitt's 48th birthday, the actor and his partner Angelina Jolie took their six kids -- Maddox, 10, Pax, 8, Zahara, 6, Shiloh, 5 and twins Vivienne and Knox, 3 -- to see Cirque de Soleil's staging of Michael Jackson: THE IMMORTAL World Tour Saturday.
Slipping into the day's early performance at the Mandalay Bay Events Center in Las Vegas, Pitt and Jolie, 36, sat with their family in the second row and even joined the rest of the audience in a standing ovation for the cast after the performance.
"The artists were pleasantly surprised by this unannounced visit," a source tells Us Weekly.
Hopefully the weekend outing will help up the famous parents' cool quotient, since Jolie has said her children don't consider them to be hip, despite their A-list status.
"Fortunately, I've scored some points at home because of Kung Fu Panda. They love Tigress, who is my alternate personality," Jolie recently told The Hollywood Reporter. "Otherwise, they think Brad and I are just so not cool."
