A huge female celebrity's alleged affair with a top sports star has seemingly been exposed after 'thousands of intimate messages and pictures leaked online'.
The woman has been described as a 'high-profile personality and entrepreneur' who is believed to be British.
A cyberstalker has allegedly used 'spyware' to infiltrate her email and social media accounts where nearly 90,000 screenshots from her mobile phone were stolen.
The pictures and messages have reportedly leaked online after the cyberstalker stored them incorrectly - which meant anyone could access it.
American cybersecurity expert and researcher Jeremiah Fowler allegedly came across the leak, which had been online for at least two weeks.
The stolen data also included invoices and receipts, as well as selfies and private chats from Facebook, WhatsApp, Instagram and TikTok.
Jeremiah has protected the woman's identity after the information claimed she had been having an affair with a 'well-known sportsman'.
He told The Sun on Sunday: 'They were both married. The type of data that was there would have been very damaging. It was clear there was an affair going on with a prominent public person.

'This information of the affair never appeared in the media but, because the files were exposed for such a long period of time, it is highly possible that someone else accessed them and may release them at a later date or attempt to use them for some sort of extortion.'
He added: 'I reported it to the police by email. The victim was notified but I don’t know if she also went to the police.'
The Daily Mail has contacted Jeremiah for a comment.
Those caught using stalkerware illegally can be prosecuted in the UK under the Protection from Harassment Act 1997.
In a blog post on the ExpressVPN website, Jeremiah penned: 'Although the case involves public figures such as celebrities and social media influencers, the underlying issue is not limited to high-profile targets.
'The same tools used in these incidents are commonly deployed in broader cybercrime, harassment, and stalking situations affecting everyday users.
'My goal in publishing these findings is to raise awareness about the risks posed by stalkerware.
'By showing real examples of what this type of software can capture, readers can better understand the seriousness of the privacy violations, ways to identify and protect themselves against it, and the potential harm that it can cause.'
