Democratic presidential nominee has time to email pillow-lipped starlet Scarlett Johansson, who admits to a crush on the Illinois senator?

Now, we're really worried.  Does't the senator have better things to do with his time?

"I am engaged to Barack Obama," the 23-year-old actress said  in January.  "My heart belongs to Barack." She joked. But she does have his email.

Though they've met only briefly, he regularly sends her email, something that astonishes the actress.

"You'd imagine that someone like the senator who is constantly traveling and constantly 'on' — how can he return these personal e-mails?" she tells "But he does, and in his off-time I know he also calls people who have donated the minimum to thank them. Nobody sees it, nobody talks about it, but it's incredible." She adds, "I feel like I'm supporting someone, and having a personal dialogue with them, and it's amazing."

He's followed her career, telling her that his favorite performance in Sofia Coppola's Lost in Translation. He's a "huge movie lover" she says and "knows who every actor is." 

But he may be only emailing the ardent, beautiful ones who profess their undying love.
