Guess who is confirmed to attend the much-awaited celebrity wedding of the year (after Angelina Jolie and Brad Pitt of course!) Plenty of A-list celebrities it would appear! The George Clooney wedding guest list was recently leaked and we now have an idea of the celebrities that would be witnessing the Ocean's 11 star finally tying the know with his lawyer fiance, Amal Alammudin.

Among those included in the George Clooney wedding guest list are Matt Damon, who is George's good friend and co-star in the Ocean's 11 franchise. Plus, U2 frontman Bono, another Ocean's co-star, Ellen Barkin (who also reportedly threw a bachelorette party for Amal), Sandra Bullock, Julia Roberts, and Brad Pitt. This report is according to a report from The Hollywood Reporter.

Aside from the star studded George Clooney wedding guest list, we had earlier news of where and when the wedding will take place. George Clooney himself, confirmed the place where their wedding will take place, during the Celebrity Fight Night In Italy Gala, which was the first red carpet event he attended with fiance Amal Alamuddin. The actor gave a speech that confirmed some crucial details of their wedding. "I met my lovely bride-to-be here in Italy, whom I will be marrying, in a couple of weeks, in Venice, of all places," said George during his speech.

As for the wedding wardrobe, those on the George Clooney wedding guest list will be the first to see the Giorgio Armani suits that the groom and his groomsmen will be wearing. A report from Women's Wear Daily says that the actor will want a Giorgio Armani design team to create what the men will wear. According to the source, "an entire team from the designer's Milan office reportedly flew up to Clooney's Lake Como, Italy, home recently to fit him and his male attendants for his September wedding to human rights lawyer Amal Alamuddin."

Now, for the much awaited wedding gown that Amal will be wearing, it's apparently by Alexander McQueen if rumors are to be believed. Amal visited an Alexander McQueen boutique in the designer's headquarters in East London. Could Amal be having a dress designed by the same man who created Kate Middleton's wedding gown?
