Ariana is a natural choice for the show, as "Problem" debuted at number one on Billboard's digital songs chart and is currently number three on the magazine's Hot 100.
The first single from Grande's forthcoming studio album has been such a success that even a teaser for the "Problem" video became a viral sensation online.
Ariana and Iggy join a list of previously announced performers that includes Miley Cyrus, Lorde, Jennifer Lopez, Pitbull and Jason Derulo.
In addition to performing at the show, Ariana is nominated for Top New Artist.
No slouch in her own right, Azalea is scheduled to perform her solo hit "Fancy." The success of that single makes Iggy the first female rapper with two songs concurrently in the Billboard Top 5.
Not too shabby. We get the feeling you'll be hearing a lot of these two this summer.
The BBMAs will be held on Sunday, May 18th.
