(Undated) -- Katy Perry's net worth is taking off like a "Firework." According to Forbes, the singer is now amongst the richest self made women in America after selling her music rights to Litmus Music late last year. The sale, which was a reported 225-million dollars, led to her net wort shooting up to 340-million dollars. The deal involved Perry's ownership stakes in master recordings, royalties and publishing rights for five albums spanning from 2008 to 2020. Perry didn't make the Forbes 2023 list of "Richest Self-Made Women in America" when it was published in June because her net worth at the time was below the threshold of 225-million dollars.
