"Miley brought an amazing, youthful energy while working with the Idol contestants this past weekend," Warwick tells PEOPLE. "Her experience in the music industry and her advice in handling fame at a young age proved invaluable."
On Wednesday's results show, Miley will return to perform her hit song, "When I Look At You," and new couple Joe Jonas and Demi Lovato will sing their duet, "Make A Wave."
"All of our contestants use what they learn from the mentors each week to carve their own path in the in the competition," Warwick says, "and Miley was no exception to this.” --Cynthia Wang
