Chris Evans and Chris Pratt have agreed to a Super Bowl bet for charity. Evans, who plays Captain America in "The Avengers", roots for the New England Patriots while Pratt, who stars as Star-Lord in Guardians of the Galaxy", is a fan of the Seattle Seahawks.

Evans was the one who started the funny Twitter exchange which led him and Pratt to agree to a bet which would benefit two children's charities Seattle Children's Hospital and Christopher's Haven in Boston. Evans wrote, "Well, well, well @prattprattpratt, looks like our teams are going into battle. For the next 2 weeks, you are not my friend, you are my enemy."

Pratt responded, "@ChrisEvans We both know there's only one Captain America and his name is Russell Wilson. #SuperBowlBound #LOB #Repeat." Evans added, "@prattprattpratt them's fightin words. Stakes? #whatisaseahawkanyway #somethingtombradyhunts."

Pratt then challenged Evans to dress as Captain America and fly to Seattle if Patriots loses to Seahawks. "@ChrisEvans OK. Seahawks win you fly yourself to Seattle, visit @seattlechildren hospital as Captain America, waving the 12th man flag," he tweeted. Evans then replied, "@prattprattpratt I accept. And when the Patriots humiliate your seachickens, I expect Star-Lord to arrive at @chris_haven in a Brady jersey."

Pratt responded, "@ChrisEvans Humiliate my Seahawks? Maybe talk to Brady about deflating your expectations. BOOM! (legion of) You're on sucka," along with a smiling emoticon.
