Hayden Panettiere once had a lesbian experience.

The 18-year-old 'Heroes' star admitted to "experimenting" with her female friends when she was growing up.

She said: "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."
