Brad Pitt and Angelina Jolie will reportedly tie the knot on 11 August 2012 - the same date as Pitt's parents Bill and Jane's golden wedding anniversary.
Up to 300 guests are expected to attend the nuptials, which are thought to be taking place at the couple's £35m French château, including Johnny Depp, Matt Damon, Tom Cruise and George Clooney.
"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," a source said.
"[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."
