Chris Evans and Ryan Reynolds have the love for each other, and someone is jealous. Robert Downey Jr. hilariously responded to the "Captain America" star's tweet that praised Reynolds' portrayal in box office hit "Deadpool".

It all began when Evans tweeted to Reynolds on Saturday, February 21, "Wow.....Deadpool was AWESOME! Well done @VancityReynolds #killedit #maximumeffort." Reynolds responded by giving a link to Evans' tweet and the hastag "#TeamCap".

Downey Jr., who played Iron Man opposite Evans in "The Avengers", later jumped into the topic and tweeted, "Et tu, D-pool? Gimme a shout when Rogers boots you out for 'cussing." He was referring to the scene in "Avengers: Age of Ultron" where the Cap had an issue with Tony Stark for saying "s**t".

Reynolds decided to respond to that, tweeeting, "We both know I can't be trusted. #TeamHelloKitty." Evans, who decided to have the last words, tweeted, "@RobertDowneyJr @VancityReynolds Bullsh*t!! The cussing was my favorite part! (just don't tell my alter ego....or Kevin Feige....or my mom)."

The Cap and Iron Man will face off each other in "Captain America: Civil War", on theaters May 6. Deadpool won't be part of the cinematic universe.
