Kellie was worse by far. It's time for her to go.
Kelli is too popular to "go." But I agree that she was one of the "worst" tonight.
That said...no one's been really bad tonight so it's gonna be hard to tell who goes.
She was, but it is not always the worst that goes. Kellie has a strong following that might save her.
Her singing is only mediocre, she needs to go home & take some voice lessons if she wants to pursue singing as a career.
