Singer Vanessa Carlton has 'outed' herself as bisexual - in front of an 18,000-strong crowd at a gay and lesbian festival in Nashville, Tennessee.

The A Thousand Miles star was headlining the Nashville Pride Festival at the city's Riverfront Park on Sunday (20Jun10) when she told the huge crowd of revelers, "I've never said this before, but I am a proud bisexual woman."

Carlton has previously been linked to rockers John Mayer and Stephen Jenkins.
