Rose Byrne Hates Melissa McCarthy's 'Abortion Of A Dress' In This Exclusive 'Spy' Clip

And why she reminds her of her mother -- in a bad way.

Need an ab workout but don't want to get up from your chair? Good, we've got just the solution: a brand new, exclusive clip from this summer's comedy, "Spy."

Directed by Paul Feig -- the man who brought you "Bridesmaids" and "The Heat," and whose upcoming all-female "Ghostbusters" reboot we're dying to see -- and starring Melissa McCarthy (who also brought you "Bridesmaids" and "The Heat," and who will lead that "Ghostbusters" reboot), there's no way you're not going to love "Spy."

McCarthy plays Susan Cooper, a CIA desk jockey who has to go into the field as a spy when the covers of all the agency's active spies are blown. She gets in deeper than she anticipated, however, when she tries to gather intel on a criminal ring involving the glamorous and deadly Raina (Rose Byrne). Watch them get stuck on a plane together in this clip, and discover why Susan reminds Raina of her mom -- and why that's not a compliment.
