Savannah Berry is well known in YouTube circles for performing cover versions of various country music hits, but on her latest video, she gets quite a surprise, as Sugarland show up to sing along on her performance of their hit single 'Stuck Like Glue.'

Well, we're sure it wasn't really a secret for young Berry, but it still had to be quite a thrill to be asked to perform alongside her heroes in this video, which promotes the upcoming ACM Awards show. Sugarland are nominated for Best Vocal Duo at the show, and 'Stuck Like Glue' is up for Video of the Year. Berry starts off performing by herself, but after a bit, guitarist Kristian Bush turns up at stage left with his guitar and singer Jennifer Nettles (uh, is that ... dancing?) comes in from the right.
