Every betrothed couple faces the same dilemma -- the difficult guest. Coleen Rooney managed to give the thumbs down to her husband-to-be's transvestite cousin, while Kate Middleton's errant uncle Gary made the guest list, no doubt under strict orders to behave.
Jolie has some awkward familial relationships. She only recently reunited with her father, Jon Voight, after a seven-year estrangement. Then there's her brother, James Haven, who she famously snogged on the Oscar's red carpet in 2000.
Both are rumoured to be invited, with Voight intending to walk her down the aisle and Haven, who is an ordained minister, expected to officiate.
But the big question is whether Jennifer Aniston will be there? In a recent interview, Brad described his ex as "giving, loving and hilarious" and she's said to be happy about his engagement.
It's a done thing in Hollywood to show you're at peace with your ex moving on -- Bruce Willis was smiling in Demi and Ashton's wedding snaps -- but given the issue of whether Brad's relationship started before or after his marriage, his ex-wife's attendance could be a step too far.
Definitely not making the cut will be Jolie's former bodyguard, Irishman Mickey Brett, who fell out of favour in 2007 after rumours that he was intending to pen a tell-all book on the pair.
