Charlize Theron thinks marriage is a "divine right" but does not want to wed herself.

The Oscar winning 'Monster' actress is pleased about a vote in New York which allows same sex couples to marry, she's doesn't believe the US government is doing enough, as it is still banned in most states.

She said: "It's a divine right and when government starts to tell us who can love and what is good love, I do have a problem with that.

"I have a problem with the fact that our government hasn't stepped up enough to make this federal, to make this legal."

South Africa born Charlize – who split with long term partner Stuart Townsend last year – enjoys being in a secure, long term relationship but personally sees no reason to have a marriage ceremony for herself.

Speaking on TV show 'Piers Morgan Tonight', she added: "I really want for myself a long-term relationship. And I have been in long-term relationships.

"That's the kind of union that I want. The actual ceremony is not something that is important to me—but I see the importance for other people."
