HAYDEN PANETTIERE & MILO VENTIMIGLIA

Panettiere and her Heroes costar went public in January, holding hands at a Los Angeles mall. Although the sweethearts – who have a 12-year age difference – aren't talking, a family friend of Panettiere's did and told PEOPLE, "They're not afraid to show their affection around her family. They kiss and she's always sitting on his lap."
