Before they were judges on NBC's hit singing competition series 'The Voice,' Adam Levine and Christina Aguilera were chart-topping singers -- and they teamed up to return to their roots Tuesday night, with a performance of their collaborative new single, 'Moves Like Jagger.'

Maroon 5 took the stage first, with Levine fronting the band for the first half of the uptempo song, before Aguilera -- wearing a low-cut T-shirt emblazoned with 'BOYS' and sporting pink streaks in her hair -- strutted on to join them for the big finish.

Written by Levine with Benny Blanco, Ammar Malik, and Shellback, 'Moves Like Jagger' was released Tuesday, and is currently in the top 10 on iTunes' singles chart.
