Hayden Panettiere sure isn't innocent.

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.”

Hayden – 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.

She added to Britain’s Glamour magazine: “I think there are some people who
like that sort of attention more than others. I used to walk my dogs in my
pyjamas and couldn’t have cared less, but you become paranoid and you get
worried.”
