Yeah. She doesn't just look too thin in that photo, she looked shockingly thin from all angles in that performance video. She needs to put on about ten pounds. She used to have more meat on her bones.
It might be her new vegan diet, but I get the feeling she's not a healthy eater. She makes a lot of comments that make it sound like she's obsessive about "healthy" eating, and sometimes people like that go overboard with restrictions.
There's also the fact that she doesn't seem to fit in meals between all the stuff she does. She'll sometimes make tweets about not having eaten anything other than mints for "the past few days."
She needs to be healthier.
