Hayden Panettiere: Hollywood Bad Girl in Training

Move over, Lindsay Lohan.

Britney Spears, you've got company.

There aren't too many wild-child, party-crazed chicks in Hollywood, really. At least among people with actual talent. From the looks of it, though, actress and 17-year-old babe in training Hayden Panettiere will not be developing into any kind of quiet type.

She's not even 18 yet (sorry, Stephen Colletti) but she's creating quite a stir, and if you're the betting sort, it seems a safe wager that wilder days are still to come.

In this collection of Hayden Panettiere photos, we've got dressed as a sexy cowgirl (yee-haw), as well as grabbing her own ass, wearing a bikini and body paint, and appearing in a, shall we say, provocative position with Heroes co-star Adrian Pasdar.

Yikes. While we shouldn't pencil her into our popular doggy style photo gallery just yet, this Hollywood hottie looks destined for bigger things.

Welcome to the club of Hollywood stars gone wild, Hayden Panettiere. We will be watching your career with the greatest of interest.
