Well, that didn't take long.
Less than a week after silver-screen superheroes Chris Evans and Chris Pratt watched the Patriots win Super Bowl XLIX in Arizona, they arrived in Boston to make good on their bet surrounding the big game.
Dressed in his Star-Lord costume from "Guardians of the Galaxy," Pratt was all smiles as he and Evans visited Christopher's Haven, a home for children battling cancer.
In the name of giving back, Pratt, a dedicated Seahawks fan, even slipped on a custom Patriots jersey and posed with New England gear.
The actor tweeted out that he was "proud" to bring his character to life for the kids at Christopher's Haven.
The visit comes after Pratt and Evans declared war on Twitter in mid-January, as their respective teams were set to battle in Super Bowl XLIX. They agreed that the loser would dress up in his superhero costume – Star-Lord for Pratt and Captain America for Evans – and visit a charity in the winner's city.
Although Pratt officially lost the bet, the two decided to team up and head to both Christopher's Haven in Boston and Seattle Children's Hospital.
