Jay-Z, Lady Gaga and country trio Lady Antebellum are close behind with six nominations, while John Legend and B.o.B received five nods each, and Drake, Cee Lo Green and the Roots earned four nominations.

Cee Lo Green's 'Fuck You' and Lady Antebellum's 'Need You Now' rounded out the category.

Eminem and Rihanna's 'Love the Way You Lie' also picked up a nominations in the Best Rap/Sung Collaboration and Best Rap Song categories, where they will face B.o.B & Bruno Mars' 'Nothin' on You' and Jay-Z and Alicia Keys' 'Empire State of Mind' again ... in both categories.
