Chris Pratt visits hospital kids with Chris Evans

"Guardians of the Galaxy" actor Chris Pratt kept his promise to dress as Star Lord and visit a charity hospital after losing a Super Bowl bet to Chris Evans.

Pratt and Evans visited sick children at Christopher's Haven here Friday, reports aceshowbiz.com.

In some of the photographs posted by the NGO, the two actors are seen posing with the children at the charity hospital.

The organisation wrote: "Chris Pratt and Chris Evans visited with the families here at Christopher's Haven in honour of the #TwitterBowl bet. The visit was complete with New England Patriots jerseys for Chris Pratt and lots of toys for the kids. Thank you to Newbury Comics and Disney for sending toys and gift bags for the kids! This was a day they will never forget."

The actors made the wager last month on the outcome of the American football final, which the New England Patriots won against the Seattle Seahawks in Arizona Feb 1.

A photograph showed the duo holding a jersey of the New England Patriots with number 49. The organisation captioned it: "@prattprattpratt didn't forget the #Brady jersey! Here is #Starlord and @ChrisEvans showing their #Patriots pride ;)."
