Poor thing, this is what happens with so many pop acts. They have to know how fickle the pop audiences are at this point. You reach a certain age and it's all downhill. This has more to do with Katy's poor choice of singles and her team overestimating her popularity, nothing to do with Gaga who's also holding on by a string with her recent flop album and singles ? just saying! She's rich, if she invested well she'll be fine, she might even come back from this disaster era.
