Red Hot Chili Peppers will join Post Malone onstage, while Miley Cyrus and multiple-nominees Brandi Carlile and H.E.R. will tilt the previously announced lineup of Camila Cabello, Cardi B, Dan + Shay, Malone, Shawn Mendes, Janelle Monáe and Kacey Musgraves toward the female side.
More to come, obviously.
