Beautiful Hayden Panettiere At CMT Artists Awards

Hayden Panettiere looked sexy as she paid a visit to MTV's TRL

Making her co-star boyfriend Milo Ventimiglia wish he were back home in the States, Hayden Panettiere was looking oh-so-sexy as she stepped out in New York City on Tuesday afternoon (September 2).

Dressed in an all-black ensemble topped off with bright red lipstick, the "Heroes" hottie made her way into MTV's TRL studios for a guest appearance on the hit show.

Hayden, as well as her fellow "Heroes" co-stars, are all spread out as they promote the upcoming September 22nd season premiere of their TV show.
