A stage name is a pseudonym utilized by performers and entertainers, such as actors, comedians, singers, and musicians. Such titles are adopted for a wide selection of reasons and may be similar or nearly identical to an individual’s birth name. In some situations, a performer will ultimately adopt their title as a legal name, although this really is often not the case. Nicknames are occasionally used within a person’s professional name.
