Nickelback stopped by the Children's Hospital of Philadelphia last week and the patients greeted the band with open arms (and hugs)! Check out the great pictures from their visit below! After the visit, Nickelback wrote on twitter: "WOW! @RyanSeacrest has this place DIALED! Full studio wired 2 all the rooms in the hospital 4 every kid to see & hear! Thanks 2 the wonderful staff @ChildrensPhila & @RyanFoundation 4 having us today! These kids are the real rockstars! These amazing kids are an inspiration to all of us! @RyanSeacrest keep up the good work with the @RyanFoundation!!" Thank YOU, Nickelback, for making it such a special and memorable day at CHOP!
