One criminally underrated hottie is the gorgeous Callie Thorne. You might not know Thorne by name but I can guarantee you know her face. She's all over television including "Rescue Me", "The Wire" and "Necessary Roughness." Ringing any bells? Of course it is. Well Callie stars in today's Hottie Clip of the Day, which comes from the flick DAVID & LAYLA. In this clip Callie does a little boxing before getting a real workout in. Man this woman is sexy!
