This year’s Grammy Awards is promising a magnificent show filled with some of the best performers and never-before-seen musical combos. We already know Gwyneth is teaming up with Cee-Lo Green, and Barbra Streisand was recently announced as a performer. Justin Bieber will take to the stage with mentor Usher and good friend Jaden Smith, while B.o.B, Bruno Mars and Janelle Monáe are sure to bring the house down when they perform. Add to the mix the always theatrical Lady Gaga, the delightful Katy Perry, Eminem and even more acts and we’ve got quite a show! There are still some performers waiting to be announced so for now check out those who are confirmed to bring us a massive Grammys party!
