Tyler asked the American Idol contestant to perform with him weeks ago
The East Brunswick, New Jersey native, 19, first got the news that she would be performing with Tyler – who is also a former American Idol judge – when she visited with the Aerosmith frontman in Nashville for a taped segment that aired earlier this season.
In fact, it was Tyler who asked Jax to take the stage with him!
On the live finale Wednesday, Tyler first did the debut performance of his new country single “Love Is Your Name” and then was joined by Jax – née Jackie Cole – on the Janis Joplin hit “Piece of My Heart.”
And they ended the performance lying in front of the judges, who gave them a standing ovation.
American Idol will return for its final season in 2016.
