It’s a common practice for celebrities to go by stage names that differ from the moniker given to them at birth, but not every stage name is as obvious. There are many reasons why celebrities change their names, some make sense while others…don’t.
1 Katy Perry was born Katheryn Elizabeth Hudson — she used her mother’s maiden name to avoid confusion with actress Kate Hudson.
2. Michael Keaton was born as the same name as award winning actor Michael Douglas.
3 Natalie Portman real name is actually Natalie Hershlag.
4 Miley Cyrus – Her parents named her Destiny Hope Cyrus, but her nickname “Smiley Miley” caught on, so much so that she legally changed her name to Miley Ray Cyrus at 15.
5 Michael J. Fox was actually born Michael Andrew Fox, but, according to Cracked, switched out the initial because the Screen Actors Guild didn’t allow duplicate names.
