Here's where hilarity continues.
In the interview, she said she was suffering from GASTROESOPHAGEAL REFLUX DISEASE, and she couldn't even speak (she spoke fine in her shit apology at the end of the show). Then she said for tonight, she got a cortisone shot to make her feel better so she could perform.
HOWEVER, cortisone isn't a solution, it increases risk for the disease to occur.

She's dumber than her sister. Just fucking admit you were using a lip synch track that night. Don't make excuses, don't blame others. Just say "Things fucked up," and be done with it. Everyone who is trying to do damage control is just making this even bigger. And I fucking love it. It's like trying to put out a fire with gasoline.
