Here's a little secret (that you may already know) but we'll tell you anyway - there's quite a lot of your favorite actors, musicians, and media personalities that don't use their real names.  The name they come up with to use in place of their real name is called a "stage name."  

What we've got here are some of the stories behind those names... or why certain stars decided to go with a stage name.  For example - Lana Del Rey?  Yeah.  Her name is Elizabeth.

Check out the photos below and get the scoop on some of those Hollywood names you know... and the real ones you may not.
