A look alike is a person or thing that closely resembles another, especially someone who looks very similar to a famous person.
Some people enjoy the attention they get from being confused with a celebrity, for instance the is a lady who is a celebrity look alike of Rihanna and she has made a career out of being a double ganger.
Speaking of a celebrity look alike, this brings me to this guy who look like the South African artist Cassper Nyovest. Refiloe Maele Phoolo, professionally known as Cassper Nyovest, is a South African rapper, songwriter, entrepreneur, record producer and part-time boxer. Born and raised in Mahikeng, North West, he is regarded as one of the most successful artists in South Africa
This caused a stir on social media, many made jokes and called him low budget Nyovest, but all in all it must be a good feeling to be confused as a celebrity.
