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.

As previously reported by Gossip Girls, Hayden’s beau Milo, as well as Masi Oka, happen to be all the way across the globe in Sydney, Australia, as they do their part to boost the latest season’s numbers.
