Maybe new fiancé Ryan Reynolds has turned her into a true romantic. Or maybe she was just sick of the criticism.

Whatever happened, Scarlett Johansson is singing a new tune about monogamy that has nothing to do with her recent album release.

“I don’t think it’s a natural instinct for human beings, but that doesn’t mean I don’t believe in monogamy or true love,” she says in the August issue of Cosmopolitan.

“I believe in finding a soul mate,” she says. “I’ve always been in monogamous relationships. I would never want to be in an open one. It’d be too awful.”

The He’s Just Not That Into You star, 23, has had to explain comments that she didn’t believe that human beings naturally settled down with one person.

Still, there’s signs of the old cynic inside that husky-voiced exterior.

“Monogamy can be hard work for some people,” says Johansson. “I don’t think it applies to everybody, and I don’t think a lot of people can do it.”
