Chris Evans' favorite children's charity gets donations boost from Pratt bet

Movie superheroes Chris Evans and Chris Pratt's friendly Super Bowl bet has helped to boost donations to the Captain America star's favorite children's charity by more than $11,000 .

The actors' hometown teams faced off in the big game on Sunday (01Feb15), with Evans' New England Patriots taking on Guardians of the Galaxy star Pratt's 2014 Super Bowl champs, the Seattle Seahawks.

Evans proposed the pals take their light-hearted rivalry to the next level by suggesting the loser would have to visit a children's hospital of the winner's choosing in character.

Pratt agreed, and their friendly jabs online helped to raise the profile of Evans' favorite charity, the Christopher's Haven facility in Boston, Massachusetts, where organization bosses have recorded an extra $11,000 in donations from fans inspired to help out.

Joyce Duvall, executive director of Christopher's Haven, tells TMZ.com, "The coolest thing about something like this is that all the kids win... no matter what happened in the football game."

Pratt emerged the loser of the bet as Evans' Patriots beat the Seahawks.

However, instead of picking one medical center over the other, the two friends have decided to treat young patients to special superhero visits at both the Christopher's Haven center, which provides a home for kids battling cancer, and the Seattle Children's Hospital.
