"One time, a boyfriend went out of town, and he left notes all over the house in places he knew I'd find them," recalled Panettiere. "And they just said little things like, 'I love you.' And under my pillow, one said, 'Sweet dreams.'"

"I don't know," Panettiere replied coyly. "I don't think I've ever said I have a boyfriend."
