Federal prosecutors are recommending a nearly six-year prison sentence for a Florida man who has pleaded guilty to hacking into email accounts belonging to Christina Aguilera, Mila Kunis and Scarlett Johansson.

Court documents filed earlier this week in California said 35-year-old Christopher Chaney also should pay more than $150,000 in restitution, including about $66,000 to Johansson. Chaney is scheduled to be sentenced July 23.

Chaney pleaded guilty to nine counts in March and was arrested last year as part of a yearlong investigation dubbed "Operation Hackerazzi."

Prosecutors said Chaney illegally accessed the email accounts of more than 50 people in the entertainment industry.

Nude photos Johansson had taken of herself were later posted on the Internet. "The Avengers" star said the photos were meant for Ryan Reynolds, now her ex-husband.
