Hayden and Milo

The two celebrities previously denied they were dating but boy, they sure can’t hide love’s glow on their faces when they are together! A source told PEOPLE magazine that “Heroes” stars Hayden Panettiere and Milo Ventimiglia are girlfriend and boyfriend.

A family friend even chirped in that “Hayden’s mom adores Milo. She thinks he’s so cute. She tells her friends that he’s her boyfriend. She’s very proud.”

Hmm, Milo sure is lucky! This early and Hayden Panettiere’s family is already impressed with him! According to reports, Milo hung out with the entire Panettiere family last December in New York City.

The source reveals, “He’s even met her grandparents. He fits in perfectly with the family. Milo jokes around with her little brother. They’re buddies.”

So, the big question now – when will the lovers officially announce their couplehood?? A rep for the actress has told People that they “do not respond to inquiries from the media regarding Ms. Hayden Panettiere’s personal life.” Hmmp! Guess we’re back to wait and see..
