Hayden Panettiere: I Swear I'm Not Dating Mark Sanchez!

Hayden Panettiere attends the Vans 2011 Custom Culture Contest on Thursday (June 2) at the Cooper-Hewitt National Design Museum in NYC.

The 21-year-old actress was one of the celeb judges who helped pick the winning shoe, which was designed by a high school student.

Over the weekend, Hayden was spotted hanging out with New York Jets quarterback Mark Sanchez but she told Us Weekly, “I swear I’m not dating him at all.”

“I’m a huge Jets fan and became very good friends with him and his buddies. There’s genuinely, absolutely nothing going on. I’ve always been that girl who has a lot of dude friends. I’m into sports so we have a lot in common, but no, definitely 100 percent not dating,” she added.
