Actor Chris Pratt will visit a paediatric cancer centre dressed as Star-Lord after losing a Super Bowl bet to Chris Evans.
The actors made the wager last month on the outcome of the American football final, which the New England Patriots won 28-24 against the Seattle Seahawks in Arizona Sunday.
As Pratt's team was defeated, he will have to dress up as the half-human half-alien, who he plays in "Guardians of the Galaxy", to visit Boston-based NGO Christopher's Haven, reports femalefirst.co.uk.
Following the game, which Pratt watched with Evans at the University of Phoenix Stadium, he tweeted: "Thank you @Seahawks for a wonderful year and congrats on you NFC championship. So close. The #12s love you!!!
"Congrats to the world champions @patriots you were the better team tonight. I will be visiting @chris_haven as Starlord. #twitterbowl (sic)"
