The former Governor of California has joined the gay and straight celebrities celebrating the Supreme Court's decision on Friday (26Jun15).

He tells WENN, "I'm very happy that they made the right decision on that because we in California of course are always a step ahead! We made that decision already a long time ago. Our Supreme Court of California said that it is unconstitutional to deny people, gay or same-sex couples, their marriage.

"Everyone has equal rights, so this is the right way to go. I think it's a great celebration for America... Sometimes, I have to say, the judges and the judiciary system makes better decisions than the politicians!"

Celebrities including One Direction's Harry Styles, gay singer Sam Smith and gay icon Liza Minnelli were among the first to celebrate the U.S. Supreme Court's historic ruling on same-sex marriage.

It means no state authorities can ban gay unions in the future.
