Hollywood hunk George Clooney celebrated his 48th birthday stumbling and throwing up at a nightclub last week, it has emerged.

The Oscar winner partied like a rock star at Blade nightclub at the Fountainebleau, and seemed to have gone overboard in drinking. "He was drinking vodka and Patron, but it looked like he'd had enough," the New York Daily News quoted a snitch as saying. The witnesses saw a "stumbling George throw up in the VIP area.”

However, the ER star has denied getting drunk. "That never happened, although I was sitting next to someone who did throw up," he said.
