"I've been training with MTV in zero gravity, eating astronaut ice cream, and I'm on a group text with Buzz Aldrin and Neil deGrasse Tyson," Perry said in a statement. "Come August 27th, I'll be ready to be your MOONWOMAN! Brace for impact, kids."
"We're thrilled to have global phenomenon Katy Perry as the host and a performer at the 2017 VMAs," Bruce Gillmer, Head of Music and Music Talent at MTV's parent company Viacom said. "She is at the forefront of music culture and the perfect person to anchor this year's show, which promises to be one of the most diverse and music-filled in VMA history."
