Hayden Panettiere spent her Valentine’s Day having dinner with all of her family. The blonde hottie, who is said to be dating Heroes co-star Milo Ventimiglia, was spotted at the new STK restaurant in Los Angeles, California, with her mom, Lesley R. Vogel, her dad Alan Panettiere and her younger brother Jansen. Hayden recently came back from the Berlin International Film Festival, where she flew to promote her new movie “Fireflies in the Garden.”
