Brad Pitt and Angelina Jolie's children have been suggesting themes for their wedding.

The couple are set to marry at their French estate Château Miraval later this summer and their kids - Maddox, 11, Pax, nine, Zahara, eight, Shiloh, six, and four-year-old twins Knox and Vivienne - have been arguing over how they should celebrate their big day.

A source told America's OK! magazine: ''Brad and Angelina made no secret of the fact that the wedding is mostly for kids. So they lined up all the siblings and asked them what kind of theme they want.

''It turned into an all out war. Maddox wanted 'World War Z' zombie compounds, Shiloh wanted a 'Monsters Inc' theme and suggested that Angie dress up as Boo, Zahara wanted a princess theme and Pax couldn't decide between zombies and monsters.''

Meanwhile, Brad is reportedly more in love with Angelina than ever and their romance - which began on the set of 2005 - is still rock solid.

Another insider said: ''Brad says he wakes up every morning and feels the same thing he felt when he first saw Angelina. He kisses her everytime he sees her for the first time that day or comes home from long day of work.

''He doesn't care if she's baking brownies and cupcakes and has batter on her face, if she has fruit pebbles stuck in her hair from that morning, he's as in love as you can ever be.

''Brad and Angelina are at a point in their lives where they are happy. They wake up every morning and feel lucky to have the family they do, fortunate that they can provide for their family - and that ultimately they are living the lives that they think inspires each of them to be the best possible versions of themselves.''
