Leonardo DiCaprio believes people shouldn't "focus" on gay marriage issues.

The 'Inception' actor - who is currently dating 'Gossip Girl' star Blake Lively - believes the issue of whether two men or two women should be allowed to legally wed pales in comparison when compared to "global warming" and other international issues.

He said: "That's the most infuriating thing - watching people focus on these things (gay marriage). Meanwhile, there's the onset of global warming and these incredibly scary and menacing things with the future of our economy."

Director Clint Eastwood - who recently worked with Leonardo on movie 'J Edgar' - also reveals he doesn't "give a f**k" about the issue.

He added to GQ Magazine: "These people who are making a big deal out of gay marriage? I don't give a f**k about who wants to get married to anybody else."

Leonardo and Clint are not the only two Hollywood stars to come out in support of gay weddings - Brad Pitt recently revealed his belief anyone should be free to marry whoever they want.

He said: "It is encouraging that New York has joined the movement to grant equal marriage rights to its citizens. But it is each American's Constitutional right to marry the person they love, no matter what state they inhabit.

"No state should decide who can marry and who cannot. Thanks to the tireless work of so many, someday soon this discrimination will end and every American will be able to enjoy their equal right to marriage."
