She'd be laughed at, mocked, booed off the stage at and be placed even further than she already is into the category of jokes of the industry. She's already been forgotten, really so there's not much for her to lose anyway since she's already considered mentally disabled trash, and a rags-to-riches tale gone wrong and has ZERO respect in the industry.
Grammys wouldn't even let her perform anyway even if she wanted to. Only REAL musicians are allowed. Ones who don't half ass choreography, have messy ass stageshows, have NO control over their careers not to mention control over their own lives and their kids' lives
and musicians who can actually hold a note for longer than a millisecond without sounding like they have stage 4 throat cancer.
this performance was better than most pop girls today. don't even try it.
