Watch all of the 2014 AMA performances.
The AMAs had a pretty stacked cast of performers this year, with a pretty wide range of pop, R&B, and rap performances. Lil Wayne debuted a brand new song from the Carter V, which featured the newly Cash Money-signed singer (and Weezy's rumored girlfriend for a time) Christina Millian. Elsewhere, Nicki Minaj delivered the first full televised performance of "Bed Of Lies", which she teased during her hosting gig at the AMAs, while Jennifer Lopez and Iggy Azalea did their best to reel in their "Booty" performance for the primetime crowd.
Later on, Ariana Grande and The Weeknd joined forces to perform their pop-infused duet, "Love Me Harder", and both Nicki and Iggy took the stage once more for "Bang Bang" and "Fancy" respectively.
