George Clooney, who has invited Barack Obama and his wife Michelle Obama to his wedding to Amal Alamuddin is waiting for the President's reply on whether they will attend the wedding or not.
A source said the Obamas would be the jewels in the crown of a celebrity guest list that already reads like a who's who in Hollywood, the Daily Star reported.
Another source close to Clooney said that the couple's big day will be refined and sophisticated unlike other celebrity weddings.
Guest lists also include Matt Damon, Brad Pitt, his partner Angelina Jolie, U2 frontman Bono, former supermodel Cindy Crawford and Sandra Bullock.
