Chris Pratt and Chris Evans may be the world's nicest celebrities

Chris Pratt dressed-up his character from Guardians of the Galaxy and visited sick children as part of a wager with fellow actor Chris Evans over the outcome of the Super Bowl.

The two actors had decided that the person whose favoured team lost the game would have to dress-up in costume either as Star-Lord (Pratt) or Captain America (Evans) and visit a children’s hospital of the winner’s choosing.

Pratt’s team, the Seattle Seahawks, lost to the New England Patriots and Pratt made good on the bet, visiting Christopher’s Haven hospital in Boston alongside Evans on Friday.

According to a statement from Christopher's Haven, the pair will soon visit Seattle Children’s hospital, the charity favoured by Pratt.

The wager was much-publicised and both hospitals have raised thousands off the back of the bet.
