(LOS ANGELES) -- Drake and Rihanna will perform a duet at the Grammy Awards, while Cee Lo Green will take the stage to sing with Gwyneth Paltrow and the Jim Henson Company Muppets.
It's unclear how the Muppets will be incorporated into the performance. Paltrow and Green recently teamed up when they sang together on Saturday Night Live last month.
The new artists taking the Grammy stage join already-announced acts Eminem, Lady Gaga, Bruno Mars and Katy Perry. The Grammys air live February 13 on CBS.
