Adams performed "To Be Without You" from last year's Prisoner alongside contestant Britton Buchanan.
Adams seemed to have the time of his life hanging out with celebrity judges like Kelly Clarkson, Alicia Keys and Maroon 5 singer Adam Levine.

It's not the first time Adams' music has appeared on the show, though — earlier this year, contestant Dylan Hartigan performed Heartbreaker classic "Come Pick Me Up."
