George Clooney and Amal Alamuddin got married in Italy. Clooney's family and A-List guests were in attendance. However, the star-studded wedding reportedly did not see the presence of Clooney's close friend Brad Pitt and his wife Angelina Jolie. There was a major rumour that Pitt would be the best man, however, Clooney's best man was reportedly his father Nick or his best friend Grant Heslov.

It is being said that Pitt and Jolie were busy shooting for their film "By The Sea" nearby Malta Island, according to reports by Daily Mail. Clooney and Pitt have done four movies together and they share good personal equation.

"We're good friends, but it's different from what people think-meaning we don't spend a lot of time together. He has been to my home in Como; we motorcycle together," Clooney once said about his friendship with Pitt to Hollywood Reporter.

Interestingly, when Jolie and Pitt got married earlier this month, Clooney and Amal were not seen in the guest list. The couple got married in a secret ceremony.

When the news of their wedding broke, Clooney told ABC News, "How great is that?!I'm really happy for Brad and Angie and their whole family."

Another friend of Clooney who was missing from the wedding was Ben Affleck. The "Batman Vs Superman" actor was unable to make it to the wedding due to promotional commitments of his movie "Gone Girl," according to the reports.

Even Clooney's "Gravity" co-star Sandra Bullock was not seen at the wedding. Bullock is currently shooting for a film in the U.S.

The guest list of Clooney's wedding included Richard Kind and Matt Damon to Bryan Lourd, Anna Wintour, Stefano Tonchi, Bono, Bill Murray, John Krasinski with Emily Blunt and Cindy Crawford with husband Rande Gerber.

Amal and Goeorge got engaged in the mid of this year. Clooney reportedly proposed to Amal over a home cooked meal with a $750,000 ring diamond ring.
