Justin Bieber is being sued by game developers after he threatened them with legal action for using his image for a mobile app.
RC3, the makers of a game entitled 'Joustin Beaver', admit the app is a parody of the 'Never Say Never' hitmaker's life, but they are reportedly keen for a judge to rule they are permitted to market the app under the free speech rule of the First Amendment.
In the company's lawsuit, obtained by The Hollywood Reporter, it states: ''In an effort to comment on the Defendant's life, the Plaintiff, RC3, developed the aforementioned App entitled 'Joustin' Beaver.'
''The App, a video game, is a parody of the commercial success of the Defendant and any celebrity.''
RC3 deny the app is an infringement of Justin's intellectual property rights or trademark.
In the game, a player has to get a cartoon beaver - who bears a resemblance to the pop singer - to sign 'Otter-graphs', while defending him from 'Phot-hogs' as they float downstream.
The 17-year-old singer's representatives previously issued a cease and desist letter to the company demanding the $0.99 app be removed from sale on iTunes and they reportedly asked RC3 to hand over their accounting and revenue figures.
