Miley Cyrus wasn't feeling well during her New Orleans concert on Saturday, January 26th. According to TMZ:
"The Disney princess, 15, was singing to a sold-out crowd in New Orleans on Saturday when she announced she wasn't feeling well and left the stage. This young girl is a trooper -- she returned to the stage and finished performing -- while seated. Her daddy, Billy Ray, was so proud -- he came out and sang with her."
