The Obama girl isn't the only one with a crush on the presumptive Democratic presidential nominee.

Actress Scarlett Johansson said she and Barack Obama are pen pals, and she couldn't be more delighted.

“You’d imagine that someone like the senator who is constantly traveling and constantly ‘on’ — how can he return these personal e-mails? 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," the blonde bombshell told Politico newspaper.

"I feel like I’m supporting someone, and having a personal dialogue with them, and it’s amazing," she added.

Joining a long list of Hollywood celebrities, Johannson has not only endorsed Obama but taken her commitment even further -- placing get-out-the-vote calls for him, headlining fundraisers and appearing in a music video written for the candidate by musician will.i.am.

Johansson said she's not telling people who to vote for, but she does want to inform young people about Obama's positions.

"I’m not telling people who to vote for, and I don’t expect that if I did it would swing votes. At least, I hope not. What I want to do is raise awareness of Obama and his policies, and share my own story of how I became involved in his campaign. Perhaps, if they’re a fan, my story might entice them to learn or spark their interest some other way. If I can answer questions or direct people to a Web site where they can get more information, that’s how I can help," she told the newspaper.
