Angelina Jolie never expected to fall for Brad Pitt...

The 32-year-old actress didn't want to date another actor following her divorces from Billy Bob Thornton and Jonny Lee Miller, but couldn't resist Brad when they starred in hit 2005 movie Mr. and Mrs. Smith.

She said: "After my last divorce, I said I was absolutely going to marry somebody in another field, an aid worker or something. Then I met Brad, everything I wasn't looking for, but the best man, the best father I could possibly wish for, you know?

"I don't see him as an actor. I see him very much as a dad, as somebody who loves travel and architecture more than being in movies."

Angelina also revealed although Brad, 44, only got involved in charity work when he met her, he always showed an interest in humanitarian causes.

She added to Vanity Fair magazine: "Brad's passion for international affairs was actually one of the things that brought us together. Though he wasn't as publicly active, I found him to be very aware of the world, very curious, very compassionate.

"In his private way, he had been doing a lot. When we met, we realised our common goals were that we both wanted to be involved in the world and see what we could do. When it comes to common goals - orphans, orphans' rights, children - we support each other. It brings us together and makes our relationship work."

Meanwhile, it has been claimed two US magazines are involved in a bidding war for the first photographs of the couple's twins.

People magazine and OK! magazine are both determined to get their hands on the exclusive pictures and are said to be willing to splash out a staggering $15 million to secure the rights.
