Justin Bieber reportedly caused havoc when filming his cameo for CSI after he was caught miming his co-star's lines and ruining their scenes.
The Somebody To Love singer, who stars as troubled teen Jason McCann in the US crime series has reportedly cost the show a small fortune after his scenes needed to be reshot every time he lip-synced his fellow actors words…on camera.
A source told the National Enquirer: "It's good Justin's got everyone's lines memorised so he knows where he's at in the scene, but the camera keeps catching him lip-synching when the other actors speak. It's hilarious - but damned expensive!"
Justin, who was only meant to feature in the season premiere of the show will now be a regular fixture on the CSI set after bosses decided to make his role permanent through the series.
A spokesperson for the show recently stated: "He will play 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."
They added: "It is the beginning of an emotional story that will conclude later in the season."
