London, Sep 14 American actor George Clooney has vowed to take revenge against his 'Ocean's Eleven' co-star Matt Damon for joking to a foreign reporter that the former is set to marry his gay partner.

Damon, 38, had recently admitted to having fuelled rumours that Clooney, 48, is gay, leading to a reporter stripping off his clothes and then propositioning him during an interview.

But now Clooney has decided to get back at Damon for the embarrassment caused, and he says that he has something planned.

"I'm going to do something. I've got something big planned," the Daily Express quoted him as saying. (ANI)
