It's safe to say a family member's attempt to extort money from Stevie Wonder was something out of the blue. The legendary singer's nephew Alpha Lorenzo Walker and his girlfriend Tamara Eileen Diaz were arrested May 2 and charged with extortion for allegedly threatening to sell "embarrassing information" about Wonder unless he gave them an unspecified amount of cash, E! News has confirmed.

Walker and Diaz reportedly tried to coerce the Grammy-winning musician to pony up $5 million by threatening to sell a story to the tabs.

The duo, who have been in jail since their arrest, pleaded not guilty to the charge, and are scheduled to appear in court May 16.

But this won't be the first time 38-year-old Walker and Diaz have seen the inside of a courtroom.

Last May, Walker racked up a grand theft charge, which he was on probation for when he was busted for extortion. Meanwhile, Diaz nabbed a charge for possession of marijuana with the intent to sell last February.

Walker is due back in court for violating his probation May 31.

Wonder's camp could not be reached for comment.
