Angelina Jolie and Brad Pitt's eldest son reportedly thinks it would be “cool” if a Transformer attends their wedding.
Brad recently popped the question to Angelina, after seven years of dating.
Their six children have wanted their parents to wed for a while and are now throwing themselves into planning the nuptials with gusto.
Maddox, ten, and five-year-old Shiloh are particularly excited.
“The kids are already coming up with ideas,” a source told the British edition of Grazia magazine. “Shiloh sketched a rainbow-coloured wedding dress the other day, while Maddox said he thought it would be cool if a Transformer was involved in the ceremony.”
Although the pair aren't thought to have made many firm plans at the moment, it is suspected that George Clooney, Matt Damon, Gwen Stefani and Gavin Rossdale will be on the guest list.
There has been much speculation about where the nuptials will take place, with the couple's French chateau now the firm favourite. Angelina apparently has a personal reason for wanting the ceremony to take place there.
“Miraval [the house] is the family's spiritual home,” another insider said. “It is the most romantic of their properties and Angelina feels an affinity with France because her late mother was of French descent.”
Angelina's father Jon Voight recently said he doesn't think she has started preparations for her special day yet.
