Scarlett Johansson returned from the Persian Gulf with a whole lot of soldiers' trinkets and a delusion of her own engagement — to Barack Obama.

"I am engaged ... to Barack Obama," Johansson joked Thursday in New York. "My heart belongs to Barack, and that is who I am currently, finally, engaged to. Yes."

Johansson, who showed her support for the Democratic presidential candidate at the Iowa caucus earlier this month, was really just deflecting a question about rumors she might be engaged (to actor-beau Ryan Reynolds).

The 23-year-old actress also talked about the warm welcome she received while visiting troops stationed in the Persian Gulf last week. Johansson dropped by U.S. bases in Kuwait on Jan. 17 and Jan. 18 as part of a USO tour in which she met about 3,500 men and women in uniform.
