Hollywood superheroes Chris Evans, who plays the role of Marvel's Captain America, and his friend Chris Pratt (who plays Star-Lord in the film Guardians of the Galaxy) made good on a friendly Super Bowl bet on Saturday visiting Seattle Children's Hospital bringing gifts and joy to young patients and their families.

Evans, a New England Patriots fan, and Pratt, a Seattle Seahawks fan, both wagered on who they thought would win the Super Bowl. Depending on the outcome, they promised to either visit the children of Christopher's Haven in Boston (Evans' charity of choice), or patients in Seattle. After the Seahawks lost, Pratt stuck to his word and joined Evans at the Boston home for kids with Cancer — and even wore a Tom Brady jersey, to sting his wound a little more.

But in true superhero fashion, they announced that both of them would visit both charities. The staff and patients were thrilled.

"I was so excited when I heard the news," said Maggie Mittelstaedt, an 18-year-old patient at Seattle Children's getting a hip replacement. "Guardians of the Galaxy and the Avenger movies are my favorites, and they were so nice to spend time with me."

The actors brought superhero toys to hand out donated by Marvel and Disney.

"Meeting them was a nice reprieve for us," said one 7-year-old's mom. "So many of our visitors are doctors, and the conversations are medical. I can't wait to watch the Captain America movie with her son. It will be like he knows him personally now."

"We were so surprised," said the mother of a boy who is receiving a bone marrow transplant at the hospital. "It gave Tyler five minutes of happiness. This situation will never be normal, but their visit helped make us feel special."

Since the initial bet began in January, Pratt and Evans also raised thousands of dollars for Seattle Children's Hospital and Christopher's Haven through TEAMPRATT and TEAMEVANS fundraising pages. (Donations will be accepted through the end of the week.)
