If she's over than I guess everyone by Katy Perry, One Direction, Baauer and Justin Timberlake are over because they were the only ones to debut higher this year
She's not as strong as she used to be, but if she plays her cards right she can gain her power back, but in no way is she close to being over
she's far from over, but she's certainly not anywhere near as big as she was during The Fame/The Fame Monster, and she definitely didn't turn out to be the massive pop star we all expected after TF/TFM was over.
