Jennifer Lopez: 'American Idol' Judges Save Jessica Sanchez

Jennifer Lopez poses for the cameras as she arrives on set for the American Idol elimination show on Thursday (April 12) in Los Angeles.

The 42-year-old entertainer became emotional during the show when frontrunner Jessica Sanchez was declared as having the least amount of votes for the week.

During Jessica‘s last chance performance, Jennifer ran up on stage and stopped her midway through the song to tell her that the judges would be using their one save to keep her in the competition.

“Gimme that mic! This is crazy … you ain’t going home! Go sit down!” Jen said.

ARE YOU HAPPY that the judges used their save on Jessica Sanchez?
