Orlando Bloom reminded the world of Katy Perry’s real name. Why she changed it
Perry’s birth name is Katheryn Hudson and she released a Christian rock album in 2001 called “Katy Hudson” before she released her breakthrough 2008 album, “One of the Boys,” recorded under the name Katy Perry. "Perry has taken her mother’s maiden name to avoid confusion with Kate Hudson," Rolling Stone reported in a 2010 profile of the singer.
