Sugarland Sings “You and I” with Lady Gaga at Grammy Concert [Video]

Last night, Grammy nominations were announced and the award show celebrated with a star-studded concert full of some of the biggest pop and country stars in the world!  And, for me, the highlight of the evening, was an unexpected duet between Lady Gaga and Sugarland!  Gaga had opened the show with her brand new song, "Marry the Night," but came back to close the show with a little help from her friends, Jennifer Nettles and Kristian Bush!  Take a listen to "You and I" and see what you think!

But Sugarland wasn't the only country act on hand for the event.  Jason Aldean performed his huge hit "Dirt Road Anthem" and got an assist from Ludacris!

And emerging country superstars, The Band Perry, were on hand as well.  Not only did they perform live on the show and rock out some Tom Petty, they learned they would compete in the Best New Artist category!

And here are the country nominees for the Grammy Awards, which will air in February!
