Former 'American Idol' champ Jordin Sparks and 'Glee' star and new solo act Matthew Morrison are set to headline the annual 4th of July celebration 'A Capitol Fourth,' which will air live on PBS on July 4 at 8pm EST.

Both Jordin and Morrison are opening acts supporting New Kids on the Block and Backstreet Boys on their co-headlining NKOTBSB summer tour and their patriotic performances for the special will go down on the West Lawn of the US Capitol building in Washington, D.C.

Ms. Sparks is busy recording her upcoming album and telling the world 'I Am Woman' with her newest single. In between 'Glee' seasons, Morrison has been promoting his self-titled debut album.

In addition to Morrison and Sparks, the bill will feature acts like singers Josh Groban and Little Richard.
