Katy Perry is an American singer, songwriter, and television personality known for her influence on modern pop music and her camp style. She has had a successful career, with her music being inescapable in the mid-2010s and her songs almost always reaching No. 1 on the charts. However, her career has had its ups and downs. Here are some key events that have happened to Katy Perry:

• Hiatus between albums: Perry took four years to release another album after "Prism" in 2013, which was a mistake. The industry changed a lot from 2013 to 2017, and pop music became less popular as hip hop began to dominate the charts. Perrys absence during those four years made the general public begin to forget about her, and when she finally came back, the musical landscape was so different that she seemed a bit behind on the times and out of touch with what was "cool".

• Producer troubles: Perrys fifth album, "Witness," was not well-received by critics or the public. Some of the blame was placed on her producer, who was accused of being controlling and not allowing Perry to be her authentic self.

• Charity work: Perry has been involved in charitable causes around the world, including being an ambassador for UNICEF since 2013 and being appointed by King Charles III to be an ambassador for the British Asian Trust, which works to tackle poverty in South Asia.

• Las Vegas residency: Perry had a Las Vegas residency called "Katy Perry: Play" that ended in November 2023. She reflected on the past two years of her time in Vegas, saying that "Play" has been "my favorite show Ive ever created".

• New music: Perry has been writing new music and has said that she is writing from a "place of love" because shes feeling so much unconditional love, that love she never knew existed. She has described the new music as "light and bright".

In summary, Katy Perry has had a successful career with some ups and downs. She has been involved in charitable causes and has recently been writing new music.
