Never let it be said that Star-Lord is slow to make good on a bet.

Just five days after the New England Patriots defeated his beloved Seattle Seahawks, Guardians of the Galaxy star Chris Pratt showed up this morning -- in costume! -- at Christopher's Haven in Boston, accompanied by Captain America's Chris Evans.

"Made good on that #twitterbowl‬ bet!" Pratt wrote his morning on his Facebook page, where he shared photos. "Starlord is proud to be in Boston today at #Christopher's Haven with Chris Evans and some awesome families."

It was the result of the friendly wager between the two Marvel stars that garnered a lot of attention, and generated $27,000 in donations to Seattle Children's Hospital and Christopher's Haven.

The deal between Boston native Evans and Seattle resident Pratt was, if New England won Super bowl XLIX, Pratt would wear a Patriots jersey and make an appearance at Christopher's Haven, a home away from home in Boston for young cancer patients and their families while they undergo treatment at nearby hospitals. But if the Seahawks won, Evans would dress as Captain America and visit Seattle Children’s while carrying a 12th Man flag.

In the end, they announced they'd be paying a visit to both charities.
