Hollywood actress Scatlett Johansson has denied reports she is supporting presidential candidate Barack Obama because she has “a crush” on him.

The 23-year-old star has long voiced her support for Obama in his race for the White House in the upcoming U.S. elections - but Johansson was recently accused of favouring the politician because of his good looks and not focusing on his policies.

But a source tells the New York Daily News that the rumours are just not true: “She is a surrogate (Obama campaigner). They’re not exchanging love letters. Everyone seems to be forgetting that she’s engaged.

“Kal Penn (actor and Obama supporter) is also a surrogate, and no one says he has a crush on Obama.” Johansson is currently engaged to Blade: Trinity actor Ryan Reynolds.
