Paparazzo

A paparazzo (plural paparazzi)[1][2] is an amateur or professional photographer who takes candid photographs of celebrities, usually by relentlessly shadowing them in their public and private activities. Celebrities claiming to have been hounded by such photographers often use "paparazzi" and even "stalkarazzi" as a derogative term. News agencies commonly use the word in a broader sense to describe all photographers who take pictures of notable people.
