Chris Evans and Captain America co-star Hayley Atwell have a super playful relationship!
In this funny YouTube video, Captain America's real-life alter ego times his attack perfectly as he gives Peggy Carter a good scare.
The two play love interests on screen, but in reality they are at war—a war waged over twitter and one that doesn't look to end anytime soon.
Evans tweeted, "@HayleyAtwell remember when this ugly guy scared the crap outta you? unfortunately i cant tweet the video because peggy says a bad word :)))."
Atwell responded, "@ChrisEvans I'm gonna get you back so hard. You are ON."
The 33-year-old hunk is a known sneak assassin, having previously scared Avengers co-star Scarlett Johansson witless on The Ellen DeGeneres Show.
Despite the fierce scare battle, Hayley and Chris are great buddies.
The two are now filming the highly anticipated Captain America: Civil War, which is set to hit theatres next summer.
