Sheila E.: I'm Rockin' the DNC ... and Bringing My Family

Sheila E.'s signed on to perform at the DNC on Thursday, but her set won't have anything to do with her dear friend, Prince -- instead, she'll be focusing on helping Hillary Clinton get Latino votes.

Sources tell us Sheila's set will feature Latin-themed music, and she'll be playing with her famous father, Pete Escovedo, and her brother, Peter ... to show the "fabric and togetherness of the Latin family and community."
