Pseudonym
Musicians, actors and performers also use pseudonyms, called stage names, both to hide their identity and to give themselves a "cooler" name. For example, rapper Sean Combs is currently known by Diddy, but used to call himself P Diddy and Puff Daddy. He says that he changed his name from P Diddy to Diddy because the name "caused confusion and he wanted to 'simplify things'."
