RiRi and the Slim Shady team up for the sequel of 'Love the Way You Lie' before the rapper joins forces with Dre for 'I Need a Doctor' and RiRi comes back with Drake.
Just after Lady Antebellum's Song of the Year win, Rihanna appears on stage in a flowing dress singing "Love the Way You Lie Part II". Eminem later spits his verses in fury on a separate stage before RiRi comes over to him and finishes their set.
The lights are turned off for a few seconds before illuminating the stage again only to reveal Skylar Grey standing at the center stage and singing the chorus of Dr. Dre's new single "I Need a Doctor". The Doc himself doesn't come onto the stage until near the end of the set.
Later, Rihanna comes back with Drake to sing her hit single "What's My Name?". Their first-ever live duet performance is introduced by P. Diddy.
