Hayden Panettiere: 'I Have Had a Lesbian Experience'

Hayden Panettiere has revealed she once shared a lesbian kiss with a female friend.

The 'Heroes' star said she experimented with her sexuality when she was growing up.

She explains, "It's great to be single. It's great to have boyfriends. Or girlfriends. There are occasions when you kiss your best friend growing up, having fun and goofing about. Like perfecting your technique."

However, the 18-year-old -- who is rumored to be dating her 'Heroes' co-star Milo Ventimiglia -- refused to talk about her love life.

She said, "People are more interested in who celebrities are dating than the events going in the world. I'm not shallow. And I'm not sharing."

The actress also revealed she doesn't care about paparazzi attention, and prefers to concentrate on her career.

"I think there are some people who like that sort of attention more than others," she said. "I used to walk my dogs in my pajamas and couldn't have cared less, but you become paranoid and you get worried."

Hayden last month revealed the female celebrity she'd most like to have an affair with would be Angelina Jolie.
