Use your imagination for a bit and imagine Hayden Panettiere, that cheerleader hottie from the hit show “Heroes,” doing the “O” with her lips. I’m sure your imagination’s running wild – admit it! Here’s the blonde beauty as she arrived at the CNN studios for a guesting at Larry King Live. Notice her cleavage getting a bit deeper! I hope boyfriend Milo V’s okay with that. Check out Hayden in her red and black number after the jump!
