Milo Ventimiglia is featured in the March 2008 issue of GQ. For the first time, the Heroes star actualy talks a bit about his relationship with 18-year-old costar Hayden Panettiere.

HALO. That's what the blogs are calling you and Hayden. Does the nickname bug you?
You know what, man, it makes me smile.

If you two are dating, why not just say so?
When you're in the public eye, you try to keep whatever you can private. People can speculate and talk. But what can you do, stop living your life?

Hayden was GQ's Obsession of the Year. Did you like those photos?
Yes, I did. They were very nice.
