Brad Pitt's 'boys-only' trip to Las Vegas with sons

Just days before the Academy Awards, Brad Pitt enjoyed a boys' getaway to Las Vegas - with his sons Maddox and Pax.

 The actor, who is nominated in the 'Best Actor' category for The Curious Case of Benjamin Button, took a rare break from fulfilling his gruelling duties as a father of six by concentrating on having fun with the older male members of his bustling brood, reports Contactmusic.

Pitt took adopted kids Maddox and Pax for a day of fun in Sin City while Angelina is spending time with the girls of the family in New York.

Jolie, who is nominated in the best actress category for Changeling, was spotted with daughters, Zahara, 4, and Shiloh, 2, house hunting in the Big Apple.

The separate trips comes just days before Pitt and Jolie will walk down the Oscars red-carpet together to find out if they'll take home a golden statuette.
