So Hayden Panettiere was on Ellen yesterday, and she flashed her panties!!! But don't go crazy, she was wearing the biggest boxer-briefs you've ever seen. Supposedly her friends dared her to put on the over-sized undies backstage, and Hayden was happy to do it. Maybe next time they can dare her to not wear any panties at all. Or a dress, for that matter. At least Hayden looked really good, showing off as much cleavage as she could. That part was hot.
Lots more High Def caps of Hayden Panettiere, her underwear, and her cleavage after the jump.
