Washington, December 3 : Brad Pitt will tie the knot with partner Angelina Jolie when it would be important for their kids.

The Hollywood heartthrob, who recently walked the red carpet with Jolie at the premiere of ‘The Curious Case of Benjamin Button’, told ‘Today’ show that the couple would say ‘I do’ if it was ‘important’ for their six children.

"If we feel it''s important to our kids, we would," Us Weekly quoted him as saying in an interview relating to his ‘Make It Right Foundation’ project in New Orleans.

“I’m really proud of this family. I look at my sons and daughters. I feel rich being around them. Each one offers so much to the mix,” he added.

Jolie too in the past had confessed to the Italian edition of Vanity Fair that the kids had asked them the reason why their mum n dad were not married.

She said: "Usually people fall in love and everything revolves around the ritual of marriage, children are an afterthought. We did everything backwards.

"But sooner or later it will be the kids who ask us [to get married]. You know, they see films and start asking questions. Such as, ''Why are Shrek and Fiona married and you''re not?''" (ANI)
