Vanessa Carlton: "I Am A Proud Bisexual"

Taking a page out of the Anna Paquin book, Vanessa Carlton has gone public with her bisexuality, RadarOnline.com has learned.

Headlining the Nashville Pride concert Saturday, Carlton announced from the stage, "I've never said this before, but I am a proud bisexual woman."

Paquin, the True Blood star who is engaged to her costar Stephen Moyer, made a similar public declaration as part of a gay rights PSA April 1.
