A celebrity (often referred to as a celeb in popular culture) is a person who is famously recognized in a society or culture.

Generally speaking, a celebrity is someone who gets media attention and most frequently has an extroverted personality. There are a wide range of ways people can become celebrities, from their profession, appearances in the mass media, beauty or even by complete accident or infamy. Instant celebrity is the term that is used when someone becomes a celebrity in a very short period of time. In some places, someone that somehow achieves a small amount of transient fame through hype or mass media, is stereotyped as a B-grade celebrity. Often the stereotype extends to someone that falls short of mainstream or persistent fame but seeks to extend or exploit it. In the 21st Century, the insatiable public fascination for celebrities and appetite for celebrity gossip has seen the rise of the gossip columnist, tabloid, paparazzi and celebrity blogging.

The rise of international celebrities in acting and popular music is due in large part to the massive scope and scale of the media industries, enabling celebrities to be viewed more often and in more places.
