This was a stunt, the girl put her original song on the fake Jessica Simpson album, so when people found it out they would hear her song and get interested. Marketing genius
I wonder where the OP found out about her existence...
As said, she was lying about collaborations with Ariana Grande and Drake in web interviews with blogging sites. Some Arianators got hyped, started talking about it, then a few did their research on her, and **** hit the fan.
