On Sunday, the music industry will celebrate the best of the best at the Grammy Awards 2011. Besides being on pins and needles to see who will win in the major categories, buzz is already building up as regards the live performances as well.

And, with such a lineup, it’s only understandable. The Hollywood Reporter has confirmation that the night’s most hyped up duets include Dr. Dre and Eminem, and Justin Bieber and his mentor Usher.

In other words, we will have two icons in their respective genres take their equally famous protégés on stage for collaborations that are bound to go down in history books.

What’s even more amazing is that this is the first time in many years that Dre takes to the stage to perform live for TV. The fact that he has a new album soon may have contributed to this.

“Continuing the annual Grammy Awards tradition of pairing A-list artists for musical collaborations, the Hollywood Reporter has learned that Dr. Dre will join his protégé Eminem onstage at this Sunday’s show (CBS, 8 p.m.),” THR writes.

“It will mark the rap icon’s first live television performance in more than a decade and comes on the heels of a stellar year for Em, who not only has the best-selling album of 2010 with Recovery, but is also up for 10 awards (he’s won a total of 11 Grammys since breaking onto the scene in 1999),” the e-zine further writes.

In a separate post, THR also reports that Usher will also be taking his protégé, teen idol Justin Bieber, for a duet on Grammy night.

“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’,” THR says.

Further details on the duets have not been released – and will probably never be, so this means fans will have to watch the awards ceremony to see them.

Other musical numbers include an all-star tribute to queen Aretha Franklin (with Jennifer Hudson, Florence Welch and Christina Aguilera), a duet by Gwyneth Paltrow and Cee Lo Green.

Previously announced performers also include Barbra Streisand, Katy Perry, Lady Gaga and Miranda Lambert.
