Marvel star Hayley Atwell’s ‘naked picture’ leaked on X-rated site.
The British actress, 36, appears naked in the “selfie” shot.
It had last night been uploaded to a seedy site which regularly features leaked snaps of stars.
And the person who posted it warned they could release further revealing pictures in the future.
They wrote: “Busty British actress Hayley Atwell appears to have just had the nude photo above leaked to the Web as part of a preview for the upcoming leaking of her full set.”
The site also makes comments which are too rude to print.
Hayley is a global star thanks to her role as Peggy Carter in Marvel’s Captain America films.
It is likely she will take action over the alleged hacking.
Sharing intimate shots of someone without their consent is a crime under revenge porn laws in England and Wales.
Anyone found guilty faces up to two years in jail.
An industry insider said: “This is a nightmare for Hayley. In recent years she has hit the big time in Hollywood, so this is the last thing she will have wanted to happen.”
Hayley enjoys a family-friendly image after appearing in kids’ films including Cinderella.
But in Netflix series Black Mirror she had a lengthy sex scene with co-star Domhnall Gleeson.
And in 2010 film The Pillars of the Earth she was seen romping with Eddie Redmayne.
Hayley is the latest star to have a personal photo leaked.
Jennifer Lawrence and Kirsten Dunst were among actresses targeted in 2014.
Brit TV stars Steph Davis and Laura Anderson also had snaps leaked.
A spokesman for Hayley declined to comment.
