The Devil Wears Prada star Emily Blunt visited with Ellen today to promote her new movie, Sunshine Cleaning. Right off the bat they get into a funny debate that I have almost daily about the differences between British English and American English.

Emily opens up about having a stuttering problem when she was younger and how it affected her, how she was able to beat the stutter, faking an American accent, and her role in Sunshine Cleaning.

Sunshine Cleaning hits theaters this Friday!
