Nathan Parrett, Pip

Adam Levine has a very tough decision on his hands.

In Monday's upcoming battle round of The Voice, airing at 8/7c on NBC, Levine will put 19-year-old Pip against 24-year-old Nathan Parrett on the sultry and soulful Amy Winehouse classic "You Know I'm No Good." Musical theater vet Pip may have pushed the buttons of all four coaches when he auditioned during week 3 — compared to Nathan, who only got Adam to turn his chair around — but from the sound of things, this sing-off promises to be a close call.
