For weeks now, handsome Heroes co-stars Hayden Panettiere and Milo Ventimiglia (now known collectively as "HayLo"), have been sparking rumors of a relationship, with reports of her split from long-time beau Stephen Colletti and the pair’s closeness at various events. One friend of Milo has revealed to OK! that "they’re definitely dating."

And though the couple has done nothing to confirm the rumors, one Heroes insider spoke directly to OK! about the headlines.

“Everyone’s asking about them!" jokes Jimmy Jean-Louis, who plays the mysterious, often-mute "Haitian" on the hit NBC show. "I see them on set, they do what they need to do and then they move on." But Jimmy does admit that HayLo would make for a pretty couple. "It would be nice. They’re both very cute, you know?”
