Angelina Jolie and Brad Pitt pressure children marriage
Brad Pitt and Angelina Jolie were under pressure from their six children to get married

Brad Pitt has revealed that wedding bells could soon be ringing for him and Angelina Jolie after their six children keep pestering them to get hitched.

The 48-year-old Hollywood actor admitted in an interview with The Hollywood Reporter that keeping their pledge to hold off on marriage until gay couples achieve the same right in the US was proving increasingly difficult, because of their children's nagging for them to tie the knot.

The Moneyball star said: "I'd actually like to and it seems to mean more and more to our kids. We made this declaration some time ago that we weren't going to do it till everyone can. But I don't think we'll be able to hold out."

"It means so much to my kids and they ask a lot. And it means something to me, too, to make that kind of commitment," he added.

However, the actor, who played opposite Jolie in the 2005 film Mr and Mrs Smith, remained tight-lipped about whether he had already proposed to his 36-year-old partner of seven years.

Instead, he insisted that it would be "just ludicrous" to be in love with someone and raising a family together and not be able to make an honest woman of her.

The couple have biological children, Shiloh, five, and three-year-old twins Knox and Vivienne. They also have adopted children Maddox, 10, Pax, eight, and Zahara, six.

During the interview, Pitt opened up for the first time about the drug addiction that almost cost him his successful acting career back in the 1990s.

He admitted that he became depressed after smoking too much marijuana, saying: "I was hiding out from the celebrity thing; I was smoking way too much dope; I was sitting on the couch and just turning into a doughnut; and I really got irritated with myself."

The heart-throb revealed that it took a life-changing trip to an impoverished community in Casablanca, Morocco, for him to quit and turn his life around.

He told the magazine: "I saw poverty to an extreme I had never witnessed before. I just quit. I stopped grass then - I mean, pretty much - and decided to get off the couch."
