Two people charged with trying to extort money from Stevie Wonder pleaded not guilty in the case on Thursday.

The singer's cousin Alpha L. Walker and his girlfriend Tamara Diaz are accused of trying to extort the Grammy-winning musician over a videotape that portrays Wonder negatively.

Walker's attorney says his client simply made a movie about his life and his actions are protected by the First Amendment.

The two were arrested in May after receiving $10,000 from Wonder's attorney in a police sting.
