Katy Perry has made several comments about Russell Brand, her ex-husband, in various interviews. Here are some of the things she has said:

• In a 2013 interview with Vogue, Perry said that Brand didnt like the atmosphere of her being the boss on tour, which was hurtful and controlling.
• Perry also said in the same interview that she felt a lot of responsibility for the end of their marriage, until she found out the real truth, which she couldnt disclose because she kept it locked in her safe for a rainy day.
• Perry has not commented on the recent allegations against Brand.

Its worth noting that while Perry has made comments about her marriage to Brand, she has not made any public statements about the recent allegations against him.
