George Clooney and Amal Alamuddin are officially husband and wife!

The couple tied the knot in an intimate, star-studded ceremony at the luxurious Aman Canal Grande  hotel in Venice, Italy, Saturday evening, Sept. 27, after sunset.

"George Clooney and Amal Alamuddin were married today in a private ceremony in Venice, Italy," the actor's rep confirmed in a statement to People.

The ceremony started at 8:00 p.m. and the couple was pronounced husband and wife at 8:18 p.m. right after they exchanged vows under an arch of imported white roses, a source told Us Weekly.

The 53-year-old actor and the 36-year-old lawyer were wed by close friend Walter Veltroni - the former mayor of Rome - in front of their family and closest friends.

Celebrity guests include Cindy Crawford and husband Rande Gerber, Matt Damon and Luciana Barroso, John Krasinski and Emily Blunt, Ellen Barkin, Anna Wintour, U2 frontman Bono and Bill Murray, according to E! News.

The wedding venue was reportedly decorated with white roses, white lilies and white carnations with hundreds of  hand-crafted flickering candles.

Following the ceremony, the bride and groom, along with their more than 100 guests, reportedly dined on a five-course meal prepared by Italian chef Riccardo De Pra and a team from Pisa, and canapés by Federico Salza. The menu included lobster, risotto, sea bass, lemon ricotta agnolotti with arugula pesto and Chianina beef with porcini mushrooms, while canapés included prosciutto and figs. Bottles of champagne and red wine were also served.

A jazz trio and a pianist also performed during the evening, and Us Weekly's source said that Murray "loved the music and put his thumbs up when it started."

Family and closest friends of the newlyweds also took the microphones to give messages to the couple. The bride's dad, Ramzi Alamuddin, put the pressure on Clooney and Alamuddin, telling them, "Now it's time for grandchildren!" according to Us Weekly.

Dan Aykroyd and Sandra Bullock also gave messages to the happy pair.

The newlyweds retired to the Aman's Alcova Tiepolo suite after the evening celebration, while other guests partied until 5:00 a.m., according to Us Weekly.
