Perry was rumored to be considered the next judge on season 12 of "American Idol", according to several reports. Perry recently addressed speculation of the possibility of taking former judge Jennifer Lopez's seat. She told The Hollywood Reporter: "People have reached out to me about the possibility of being involved, and it's not right for me yet. It's a real commitment to be on one of those shows." She added: "I have ideas for two or three big, creative things, and I want to be able to fulfill those ideas."
Katy Perry recently made headlines when her famous "spinning peppermint" bra had been declared a hazard by her insurance company and banned from future stage shows.
The pop star admitted that her wigs have been getting stuck in the rotating candy-inspired bra attached to her dress while she previously performed on stage.
27-year-old Perry told The Sun that her insurance company has banned her from wearing the item during her performances due to concerns about the high levels of strain on her neck. Insurers fear that the bra will cause the pop star to pull a muscle which will lead her to cancel future performances. A missed performance can cost millions to tour operators and their insurers .
