Anna Paquin, star of the HBO supernatural drama True Blood, asserts she's bisexual, despite her marriage to Stephen Moyer.

The 31-year-old Paquin first publicly came out bisexual in a 2010 PSA for the WeGiveADamn campaign.

“I'm Anna Paquin. I'm bisexual,” she said in the PSA. “And I give a damn.”

Paquin married her True Blood co-star Stephen Moyer on August 21, 2010. Together they are raising four children, including fraternal twins Charlie and Poppy born in September 2012.

A tweet she sent last month reasserting her bisexuality and in support of marriage equality attracted headlines.

“Proud to be a happily married bisexual mother,” she messaged her more than 99,000 followers. “Marriage is about love not gender.”

During a recent appearance on Larry King Now, Paquin explained her sexuality to host Larry King.

“Are you a non-practicing bisexual?” King asked.

“Well, I am married to my husband and we are happily monogamously married,” she answered.

“But you were bisexual?”

“I don't think it's a past-tense thing,” she replied. “Are you still straight if you are with somebody? If you were to break up with them or if they were to die, it doesn't prevent your sexuality from existing. It doesn't really work like that.”
