Actress Rose McGowan has said passage of California's gay marriage ban, Prop 8, broke her heart.

The 37-year-old McGowan is best known for her role playing Paige Matthews for four seasons on the supernatural television series Charmed.

She stars as the powerful witch Marique in Conan the Barbarian, which opens in theaters on Friday, August 19.

In an interview with gay glossy The Advocate, McGowan, who was raised in a gay-friendly household and whose sister is a lesbian, said she stood alongside Prop 8 protesters.

“I was furious with how horribly the whole Prop. 8 campaign was run in California,” McGowan said. “It broke my heart the night Prop. 8 passed. I'm out there on Santa Monica Blvd. with crowds of people, and the world is watching, but all the anti-Prop. 8 protestors did was put up the same non-telegenic people with the same speeches, not understanding how it works. Their money was totally mismanaged. I really want California to get it together like New York has.”

McGowan added that she would feel like a “hypocrite” if she married and her sister and gay friends could not.

“Before I broke up with my fiancé, it seemed absurd to have my sister at a wedding that she couldn't have if she wanted to. I would still have great hesitation about getting married. I'd feel like such a hypocrite, walking down the aisle past all of my best friends who can't,” she said.
