After filming a video for her new song “Walk of Fame,” the singer caught an infection that wasn’t exactly a party in the USA.

"I thought Sabrina and Chappell both at the Grammys this year, it was over the top pro singing," she said. "I'm just big fans and I just support those girls all the way." Cyrus continued to applaud their Grammy sets because "there is so much pressure on live performance" and she knows first-hand "the courage that it takes and I know that the nerves get in the way" when taking the stage.
