Clooney would choose Pitt for his best man: Starla

She said his parents Nick and Nina Clooney are planning a trip to Europe to help with the wedding preparations

Actor Brad Pitt will be George Clooney's best man at his wedding.

The "Monuments Men" actor is set to tie the knot with girlfriend Amal Alamuddin later this year, and his aunt Starla thinks his "Burn After Reading" co-star will be by his side at the ceremony, reports contactmusic.com.

''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," said Starla.

Starla also revealed her nephew is set 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 wedding preparations for his big day.

''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," she said.
