ANGELINA JOLIE WANTED BRAD PITT FOR SALT ROLE

Brad Pitt rejected a cameo role opposite partner Angelina Jolie in her new spy thriller Salt - because he had to babysit the couple's six kids.

The actress was campaigning for Pitt to perform a motorcycle stunt for a short scene in the action film - marking the first time the couple would have shared the big screen since 2005's Mr. + Mrs. Smith.

But the complicated stunt work would have required too much time to film - so Pitt happily agreed to stay at home with the tots.

Jolie tells USA Today, "He was almost going to be the motorcycle guy that I knocked down, and then he'd call me a bad name. But he was with the kids that day, and we couldn't work it out."
