HAYDEN WORKS ON HER FITNESS

Hayden Panettiere was none to happy at being ambushed by the paparazzi trying to get a picture of her jogging with an adorable pooch Thursday afternoon outside of her $2.63 million Hollywood Hills home.

The Heroes hottie has two dogs — a brown lab-mix named Penny Lane and a small white pup named Madison. Could the mystery pup be boyfriend Milo Ventimiglia’s dog?

Clad in trendy Lululemon sweatpants, camera-shy Hayden was a little red in the face from her run and tried to cover up on the way home.

Evidently, someone has yet to inform the often glammed up actress that she looks best when she’s playing the role of girl-next-door.
