See Rihanna, Kanye and Paul McCartney In Grammys Rehearsals

Paul McCartney, Rihanna and Kanye West.

It's RIHearsal time! Ahead of Sunday's Grammy Awards, Rihanna teased fans with an inside look at her rehearsals with Kanye West and Paul McCartney.

Rihanna, Yeezy and the former Beatle are slated to world premiere their collaboration, "FourFiveSeconds," at the awards show. And judging by the rehearsal shot, their performance looks like it might take some cues from the single's sparse video, which debuted earlier this week.

"FourFiveSeconds" is the lead single off Rihanna's forthcoming eighth studio album.

Kanye will not only be taking the stage with Rihanna and McCartney, but he's also been tapped to perform again in "a never-before-seen solo performance."

Other Grammys performers include Madonna, AC/DC, Ariana Grande, Pharrell, Sam Smith, Usher and Miranda Lambert, Eric Church and Ed Sheeran.
