Brad Pitt and Angelina Jolie will marry this year on 11 August, it has been reported.
The couple, who have six children together, confirmed their engagement earlier this month.

Up to 300 guests, including George Clooney, Matt Damon and Johnny Depp, are expected to attend the ceremony at the couple’s £35million French château.

tied the know already
An insider told the Daily Star:
"They thought their kids would love the idea of seeing mom and dad get hitched followed by a big bash for them as well as 'Meemaw and Grandpa' as they call Brad's folks.
"[Jolie] came up with the idea of making it a real family celebration by merging Bill and Jane's special day with theirs.
"Brad's family mean a lot to Angelina, especially since she lost her own mum Marcheline to ovarian cancer more than five years ago and spent years refusing to talk to her father.
"The kids have been asking when they're going to get married for years. Now they are pretty much the main reason Brad and Angelina are tying the knot."
Their children, Maddox, ten, Pax, eight, Zahara, seven, Shiloh, six, and twins Knox and Vivienne, three, are said to be heavily involved in the wedding celebrations.
