True Blood star Anna Paquin say bisexuals suffer from discrimination.

The 28-year-old who plays Sookie Stackhouse on the increasingly gay-inclusive HBO vampire hit True Blood, announced she's bisexual soon after she became engaged last year to co-star Stephen Moyer, who plays vampire Bill Compton.

In a Give A Damn video ad to benefit singer Cyndi Lauper's anti-homophobia group True Colors, Paquin said, “I'm Anna Paquin. I'm bisexual. And I give a damn.”

The revelation created such interest that the website hosting the video crashed due to “enormous traffic,” the AP reported.

Nevertheless, in the July issue of fashion glossy V Magazine, Paquin stated that nobody cares about her sexual orientation.

“Frankly no one had eve asked me before,” Paquin said.

“There is a lot of prejudice against us but the more people talk about it, the less of a deal it will be,” she added. “Who people choose to sleep with – or spend their lives with – shouldn't matter, not that anyone particularly cares who I'm attracted to.”

In True Blood's season 3 premiere, Rutina Wesley's Tara revealed she's in a lesbian relationship.
