She looks like she downed some "liquid courage" before she was carried () to the stage and that contributed to her "Give-No-F*cks-Itis," but, still, I don't understand how she just didn't/doesn't give a sh*t about how that performance and how she was acting looked to the public.
Why sign up for a gig if you don't want to do it? (because: money I know but, if you're just going to be difficult and/or cancel, why commit to it?). Why waste everyone's time, energy, and money?
Speaking of which, I wonder how much she got paid for that "performance" and if they got a refund.
