Hayden Panettiere Dating Mark Sanchez?

Hayden Panettiere is reportedly dating Mark Sanchez.

The 'Scream 4' actress - who recently split with her heavyweight champion boxer boyfriend Wladimir Klitschko after 18 months - was spotted with the 24-year-old New York Jets quarterback in Laguna Hills, Caliornia yesterday (30.05.11) where they visited In-N-Out Burger with another couple.

A source told Nydailynews.com: "They seemed very close and very happy. When they walked out of the fast food restaurant, Mark was flashing a huge smile."

Hayden, 21, and 35-year-old Wladimir - who was raised in the Ukraine but is based in Hamburg, Germany - recently revealed their break-up was caused by the pressures of having a long distance relationship.

Hayden said: "While we decided to split, we feel great sympathy and respect for each other and will surely stay close friends."

Wladimir added: "We had a great time together. But more and more we saw how difficult it is to maintain a relationship when living on two continents . I cherish Hayden as a person and woman. I'm sure we will stay friends."

Wladimir - whose brother Vitali Klitschko is also a world champion boxer - is currently in training for his heavyweight title unification bout with British fighter David Haye which takes place at the Imtech Arena in Hamburg, Germany, on July 2.
