Jennifer Lopez closed the American Music Awards in a very sexy way on Sunday at the Nokia Theatre L.A.

The 45-year-old stunned on stage in a risqué bodysuit as she performed her upbeat tune "Booty." Iggy Azalea, who appears on the song's remix, joined Lopez on stage wearing a similar outfit.

Of course Lopez flaunted her "big, big, booty" and Iggy even spanked it.  

After Iggy left the stage, Lopez ended the performance with a flawless dance routine.
