Chris Pratt will visit a paediatric cancer centre dressed as Star-Lord after losing a Super Bowl bet to Chris Evans.
The actors made a 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 last night (01.02.15), and as Pratt's team were 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 Christopher's Haven.
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)"
Evans also took to Twitter to pay tribute to his team and in particular their quarterback Tom Brady - who was awarded with the MVP (Most Valuable Player) prize after the game - and revealed he would also be at Christopher's Haven on the day his fellow actor goes dress as Star-Lord.
In a series of tweets, he wrote: "Thank you to @prattprattpratt for being a good sport. I'll be there with you at @chris_haven, and don't worry @seattlechildren, we'll be
"coming there too! And lastly, I don't think anyone can ever doubt the mental toughness of Tom Brady. Tough couple weeks, but he showed why
"he's the greatest of all time. #PSIdonthearyounow #anyballanytime (sic)"
On January 19, Evans jokingly tweeted that Pratt was going to be his "enemy" until their two teams had done battle in the Super Bowl.
He 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 (sic)"
