George Clooney Has Boozy Bachelor Party To Mark The End Of His Single Days Before Wedding To Amal Alamuddin

George Clooney marked the end of his LONG era as a single man by having a boozy bachelor party, according to reports.

Pals of Hollywood’s most famous bachelor, 53, threw Clooney the stag event on Friday night in Venice, Italy, as he prepared to walk down the aisle with fiance Amal Alamuddin.

For his bachelor party, the Ocean’s Eleven star got tipsy at one of his favourite Venice eateries, Da Ivo restaurant.

Clooney was joined by a group of close pals, including his producing partner Grant Heslov and his rumored best man Rande Gerber (husband of supermodel Cindy Crawford).

Restaurateur Gerber reportedly bought several bottles of tequila for the guys and they supplemented the hard liquor with glasses of vintage Sassicaia red wine that goes for more than $400 a bottle.

The restaurant’s owner Giovanni Fracassi, a friend of Clooney’s, reportedly gave the actor the red wine as a wedding gift.

Clooney thanked Francassi, writing a note on an empty bottle of wine that he'd had “the perfect night.”

“George told me how happy he was that he was getting married,” Francassi later told a reporter.

“There were no speeches but the group enjoyed the occasion and they were all drinking tequila.”

Not surprisingly, Clooney showed up for breakfast on Saturday -- with Gerber, 52, and Crawford, 48 -- at the Belmond Hotel Cipriani wearing dark glasses!
