American Idol saved the best audition moment for their last and final season. Nashville native Tristan McIntosh, 15, showed up to the Idol auditions with her guitar and a heavy heart. She may have had great supporters cheering her on, but she still wished her mom could be there with her, too.

"Me and my mom are like really close," Tristan said, "She kind of knows me better than I know myself, and it's just a really weird feeling that she's not here for something of this magnitude."

Tristan performed Mickey Guyton's "Why Baby Why" while playing the piano. Jennifer Lopez compared the young vocalist to superstar Alicia Keys, and also said she believes Tristan's military mom would be proud. After the judges praised her talent, Tristan got an incredible surprise. Her military mom all the way from Middle East, came around the corner to surprise her. The moment was full of emotions even judge Keith Urban teared up.
