Northern Irish actor Jamie Dornan says the world's leading showbiz stars should quit using social media to stop a repeat of this week's "disgusting" nude pictures leak.
Dornan, who plays bondage-loving businessman Christian Grey in the upcoming film adaptation of Fifty Shades of Grey, couldn't hide his distaste after hackers stole nude photos of 101 famous women including actress Jennifer Lawrence and model Kate Upton.
The large-scale breach has sparked outrage in Hollywood amid an FBI investigation, and prompted calls for legal action against the hackers.
But Dornan says it's impossible to guard against cyber-crime, and the 32-year-old actor is now urging all famous women to avoid using online storage devices to hold their private photographs.
"What can you do? It's sort of disgusting," Dornan said at the GQ Men of the Year Awards in London on Tuesday.
"I don't know how they are going to keep control over it but there seems to be so many different ways that your information can be accessed.
"I think the thing to do is step away from social media if you can."
Other celebrities at the event also sent their sympathy to those caught up in the furore, with pop star Jessie J saying describing the leak as "really awful".
"I think that nobody deserves to have their privacy tampered with. I think everyone deserves their sanity, and sanity is privacy," the Bang Bang singer said.
"You need something for yourself, so I hope that it's sorted and it doesn't happen again."
Downton Abbey actor Dan Stevens, whose former co-star Jessica Brown Findlay was was among those affected by the leak, said the hacker's behaviour was "despicable".
"I think the practice of human online behaviour has to evolve," Stevens said.
"I think people are behaving in a way online that they never would in real life and it's creating a warped new reality. It's very, very frightening."
Actor Douglas Booth, who was recently rumoured to be dating Miley Cyrus, said the breach "should be treated the same way as sexual assault".
"I think it should be treated criminally and I hope that the person goes to prison for a very long time," he said.
