Teen singer Justin Bieber is to make his acting debut in the new series of 'CSI: Crime Scene Investigation'.
In a statement, US network CBS said Bieber will play Jason McCann, who is described as "a troubled teen who is faced with a terrible decision regarding his only brother - a decision that leads him into an explosive confrontation with the CSIs".
Bieber will make his debut in the season premiere and his storyline will continue during the series.
CSI executive producers Carol Mendelsohn, Don McGill and Anthony Zuiker said: "Every 20 years, a phenomenon like Justin Bieber graces our world. We'd like to believe that the phenomenon of 'CSI' has had the same impact on popular culture.
"The opportunity to bring them together in the premiere is a great treat for our audience and all of its new viewers. We're looking forward to Justin's dramatic star turn, not only in the premiere, but in a continuing seasonal arc [storyline]."
The new series of 'CSI' begins on American television on Thursday, 23 September.
