Justin Bieber, Usher team up for Grammy performance; Eminem, Dr. Dre join in, too

usher-bieber-getty.jpgBromance will be in the air on Sunday's (Feb. 13) Grammy broadcast.

Justin Bieber will share the stage with Usher, whom he has often described as a "big brother," in a performance at the 53rd annual Grammy awards. The two have paired up before for Bieber's "Somebody to Love" remix, and of course Usher is featured prominently in the Biebs' biopic "Never Say Never."

In another mentor, mentee performance on Sunday, Dr. Dre will join his own protoge, Eminem, on-stage in his first television appearance in over a decade according to The Hollywood Reporter.

That is, unless you count his "Trust me, I'm a doctor" Dr. Pepper commercials. Which obviously, we do.
