Justin Bieber to Duet with Usher at Grammys

Two days after his 3D movie Never Say Never opens wide, teen superstar Justin Bieber will hit the stage with the man he says is "like a big brother," Usher.
Like the much anticipated performance by Eminem and Dr. Dre on Sunday's Grammy Awards, Bieber and Usher will duet during the broadcast (CBS, 8 p.m.). Of course, it won't be the first time they've sung together. Usher was featured on a remix of Bieber's "Somebody To Love" (see video) and also makes a stage appearance in Never Say Never, but it's their mentor-protege relationship that has a starring role in the film, and also inspired THR's cover story this week. Says Bieber: "The best advice Usher's given me is to stay humble."
Other pairings on deck for Grammy night include Gwyneth Paltrow's duet with Cee Lo and the Muppets on "F--- You," and an all-star tribute to Aretha Frankin featuring Christina Aguilera, Jennifer Hudson and Florence Welch
