Might Emily Blunt portray Natasha Romanoff in Iron Man 2?

The character is a Soviet super spy that doubles as Black Widow, a beauty in a skintight black costume that is enhanced by high-tech weaponry.

If verified, Blunt will join the previously-announced villains Mickey Rourke and Sam Rockwell in the sequel.

Blunt's film resume includes The Devil Wears Prada, The Jane Austen Book Club and Charlie Wilson's War.

Iron Man 2 is scheduled for a May 7, 2010 release.
