A man who hacked the email accounts of Hollywood stars including Mila Kunis, Scarlett Johansson and Christina Aguilera, has been jailed for 10 years.
Christopher Chaney, 35, leaked nude pictures of actress Johansson onto the internet. The images were meant for her then-husband Ryan Reynolds.
Singer Aguilera said in a statement issued before the sentencing that Chaney's actions were "a large invasion of privacy".
US District Judge S James Otero sentenced Chaney in Los Angeles after hearing from a tearful Johansson in a videotaped statement.
The hacker pleaded guilty to counts that included wiretapping and unauthorised access to a computer.
Prosecutors said Chaney had accessed the email accounts of more than 50 people in the entertainment industry between November 2010 and October 2011.
Aguilera, Kunis and Johansson agreed to have their identities made public with the hopes that the exposure about the case would provide awareness about online intrusion.
Some of Aguilera's photos appeared online after Chaney sent an email from the account of her stylist, Simone Harouche, to the singer asking her for scantily clad photographs, prosecutors said.
Chaney was arrested in October 2011 as part of a yearlong investigation of celebrity hacking that authorities dubbed "Operation Hackerazzi."
Chaney also targeted two women he knew, sending pictures of one former co-worker to her father.
The women said their lives have been irreparably damaged by his actions - one said she suffered from anxiety and panic attacks and the otheris depressed and paranoid.
