The Grammys have added more performers to its Feb. 8 lineup.

The Recording Academy revealed Tuesday that fellow The Voice coaches Gwen Stefani and Adam Levine will perform together. Meanwhile, it appears Grammy producers have joined the industry elite insisting on making Lady Gaga and Tony Bennett stick as a duo, as the pair will also perform together during the ceremony.

They join previously announced performers Sam Smith, Pharrell, Usher, Miranda Lambert, John Legend, Common, Ariana Grande, Ed Sheeran, Madonna, AC/DC and Eric Church.

Taylor Swift and Rihanna have also been rumored to perform, although neither has been confirmed.

Of note: Surely Stefani and Levine's performance will be better than their sleepy Maroon 5 duet "My Heart Is Open." Also, if Rihanna does in fact take the stage, it will be interesting to see if she performs her Kanye West-Paul McCartney collaboration "FourFiveSeconds," considering West has famously boycotted the Grammys in past years.

Update (Jan. 28, 9:05 a.m. EST): Hozier has been added as a performer; he'll be joined on stage by Annie Lennox. Jessie J and Tom Jones will also perform together.
