Angelina Jolie has revealed her partner Brad Pitt could not face kissing her on the set of her new film when she was dressed as a man.

"I asked Brad to come to set and see if he could spend lunch with me and hang out with me and I dared him to kiss me and he couldn't," the actress said.

In Salt the mum-of-six plays as a CIA officer on the run after she is accused of being a Russian sleeper agent.

Her character dresses up as a NATO officer for part of the story, which she enjoyed: "I loved it, I found it very strangely empowering in a very different way. I had to walk through a hotel lobby dressed as a man and it was very strange to have different reactions from women than you normally have and different reactions from men that you normally have.

"I was dressed in a NATO uniform so the men kind of gave me room and respect and I got a few women flirting. I liked my guy."
