In fact it was Miley's ONLY interview of the night!
The two started it off by complimenting each other on their respective outfits.
Talk about sisterly love! We especially love the fangirling over Austin Mahone for their younger sister, Noah!!
In fact, the two had SUCH a bond on the red carpet, it looked like Brandi got Miley to open up about Lady GaGa - and she gave her quite the diss!
Check out what Miley said AFTER THE JUMP!!!
