STAGE TUBE: GLEE's Amber Riley Sings National Anthem at DNC!

The 2012 Democratic National Convention is in full swing in Charlotte, North Carolina, and just yesterday, GLEE star Amber Riley kicked things off by singing the National Anthem. Check out her performance below! 

Riley stars as 'Mercedes' on FOX's GLEE, which returns for Season 4 on September 13. GLEE is a musical comedy about a group of eager and ambitious students who strive to outshine their singing competition to win Nationals while navigating the cruel halls of McKinley High. Since its debut, GLEE has become a bona fide cultural phenomenon, received prestigious honors including the Golden Globe and Peabody Award and singlehandedly made glee clubs cool again.
