George Clooney celebrates upcoming fatherhood with tequila

George Clooney had a guys’ night out with Rande Gerber and two pals to celebrate his impending fatherhood, spies said.

The Oceans Thirteen star — whose wife, Amal, is pregnant with twins — was at West Hollywood showbiz haunt Craig’s, where “it got rowdy,” a spy said.

“They were doing shots” of Clooney’s tequila, Casamigos, and “there were lots of jokes about what George is going to do when he has two kids. They were asking him, ‘What are you going to do when you’re working and you can’t get any sleep?’ ”

Also at the eatery were Hustler mogul Larry Flynt, “Alias” star Michael Vartan and Backstreet Boys A.J. McLean and Howie D .
