Brad Pitt: Our Wedding Will Happen 'Soon'

Put the champagne on ice. It appears Brad Pitt and Angelina Jolie's long-awaited wedding isn't far off – and that's from someone who would know.

"I am getting more pressure from my kids, and it is something I want to do within their lifetime, but I also feel like the time has come," Pitt said Monday night at the premiere of his new film, Killing Them Softly, hosted by the Cinema Society in New York.

"The time is nigh," he added. "It's soon. I got a good feeling about it."

Pitt, 48, who has been in London filming World War Z this month, has been with Jolie, 37, for seven years. They have six children together – Maddox, 11, Pax, 8, Zahara, 7, Shiloh, 6, and 4-year-old twins Knox and Vivienne – and got engaged this past spring.

And yet, even with so much history together already, Pitt says the idea of tying the knot with his longtime partner is still hugely meaningful.

"We've had a family, we've raised the kids," he says. "I am surprised how much [marriage] meant to me once you had that."
