A man who hacked into the personal emails of Scarlett Johansson, Mila Kunis, Christina Aguilera and a number of other women has been jailed for 10 years.
Christopher Chaney pleaded guilty to offences that included wiretapping and unauthorised access to a computer.
Prosecutors said Chaney, 35, illegally accessed the email accounts of more than 50 people in the entertainment industry between November 2010 and October 2011.
His arrest came after an 11-month investigation - dubbed Operation Hackerazzi - into the hacking of dozens of celebrities, of whom actresses Johansson and Kunis, and singer Aguilera were the highest-profile names.
The court heard a tearful videotaped statement from Lost In Translation star Johansson after nude photos, taken herself and meant for her then-husband Ryan Reynolds, were placed on the internet.
Aguilera said in a statement issued days before the sentencing that although she is often in the limelight, Chaney had taken private moments from her.
"That feeling of security can never be given back and there is no compensation that can restore the feeling one has from such a large invasion of privacy," Aguilera said.
Chaney also targeted two women he knew, and reportedly sent naked pictures of a former colleague to her father.
Those women said their lives have been irreparably damaged by Chaney's actions and called him "creepy".
One said she has anxiety and panic attacks, while the other said she is depressed and paranoid.
Explaining how the hacking began, Chaney said: "It started as curiosity and it turned to just being addictive ... seeing the behind-the-scenes of what's going on with the people you see on the big screen."
He denied having had any criminal intent, saying: "I wasn't saving the emails to blackmail someone."
