Brad Pitt will be best man at George Clooney's wedding. The 'Monuments Men' actor is set to tie the knot with girlfriend Amal Alamuddin later this year, and his aunt thinks his close friend and 'Burn After Reading' co-star will be by his side to offer support at the ceremony Starla Clooney said: "I would say he'd choose Brad Pitt for his best man. They are good friends, I would think that's who he'd choose." Starla also confirmed her nephew is planning to marry the 36-year-old lawyer in Italy, with his parents Nick and Nina Clooney planning a trip to Europe to help with the preparations. She said: "I did hear Cincinnati, since it's not that far from Kentucky - that's one of the places they were considering - but apparently Cincinnati didn't win, it's not going to be the place. "I do know that Nick and Nina are planning a trip over to Italy in the next week or so to, I guess, scope out some stuff."
