Miley Cyrus is giving fans an update on her godmother, Dolly Parton, amid the legendary country music singer's recent health troubles. "She's always going to keep the show going - the show must go on - so she's just excited to get back to work," Cyrus, 33, told Entertainment Tonight while attending the Los Angeles premiere of Avatar: Fire and Ash last week. Back in September, the iconic country star announced she was forced to push back her Las Vegas shows by nearly a year due to her health.
