Maybe they're born with it...or maybe they were born with a completely different name!
We don’t really get a say in what we're named at birth, so quite a few celebrities have chosen to take matters into their own hands.
You might be surprised to learn just how many celebs have opted to change their names before they hit it big in Hollywood. Stars like Jennifer Aniston, Meghan Markle, and Natalie Portman all chose to make a switch.
Whether it was due to a complicated last name, to pay homage to a loved one or just because another celeb had already claimed their name, these stars all chose to change things up.
Find out which celebs opted for alternate monikers!
