Actors Chris Pratt and Chris Evans, who play Starlord and Captain America, made a Superbowl bet that involved raising money for children's charities.
In their bet, dubbed the 'Twitterbowl', Chris Pratt bet on the Seattle Seahawks to take the cup.
Following their defeat to the New England Patriots, Pratt tweeted:
"Congrats to the world champions @patriots you were the better team tonight. I will be visiting @chris_haven as Starlord. #twitterbowl"
Christopher's Haven is a not-for-profit that "provides supportive housing for families whose children are receiving outpatient pediatric cancer treatments in Boston".
Not to be outdone, good sport Chris Evans promised that he would also appear as Captain America, and added that the duo would make an appearance at Seattle Children's Hospital.
The football fans are due to appear at Christopher's Haven tomorrow, February 3rd, and are encouraging people to donate to the worthy causes.
