Pop diva Christina Aguilera and Colombian international sensation Shakira are the only two females to grace The Voice’s big red chairs. And both ladies have also rocked the stage during the coaches’ performance that kicks off each season.

Despite being five to six months pregnant at the time, Shakira rocked her performance of The Beatles’ “Come Together” with Adam Levine, Usher, and Blake Shelton. Dressed in a sequin top, leather leggings, and heels, the belly dancer owned the stage, even pulling out a harmonica at one point.

Christina’s performed a total of four times with her fellow coaches. In Season 1 the foursome sang Cee Lo Green and Gnarls Barkley’s “Crazy.” Then in Season 2 they sang a Queen medley, and in Season 3 they gave two performances, “Start Me Up,” and, “Time of Your Life,” to close out the season.

But it was Xtina’s performance ensemble in the Season 3 opener of The Rolling Stones “Start Me Up” that really turned heads. The pop icon rocked one of her signature one-piece bustiers with silver tassels.
