Our fave worst role model is at it again with her micro-wardrobe! The fit songstress flaunted her AB-solutely flat belly — and a little underboob — during rehearsals.
But her clothing isn't the only thing we notice getting smaller and smaller…
There is no denying gurlfriend does look insanely svelte, but perhaps her nonstop schedule and illness is making her a bit too thin.
We love a little booty and her frail frame is rockin', but it definitely isn't bootylicious!!!
Hopefully the family dramz isn't causing her so much stress that she's forgetting to take care of herself!
