Even more artists are expected to take the stage at this year’s Grammy awards. Previously announced acts included Beyonce, John Legend, The Weeknd, Bruno Mars, Chance the Rapper, Alicia Keys, A Tribe Called Quest, Andra Day and more. Yesterday CBS announced that Katy Perry and Lady Gaga are also slated to perform. Of course Drake, Justin Bieber and Kanye West will not be there because they are boycotting the Grammy’s for the lack of diversity. The Grammy’s will air this Sunday at 8PM.
