Evans, Pratt make Super Bowl bet for charity

Actora Chris Evans and Chris Pratt have agreed to a Super Bowl bet for charity.

Evans, who plays Captain America in "The Avengers" is supporting the New England Patriots while Pratt, who stars as Star-Lord in "Guardians of the Galaxy", is a fan of the Seattle Seahawks, reports aceshowbiz.com.

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. @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," Pratt 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."

To that, Pratt said: "@ChrisEvans Humiliate my Seahawks? Maybe talk to Brady about deflating your expectations. BOOM! (legion of) You're on sucka (sic)."
