The pictures were reported stolen by The Sun and included shots of her sister Kate who is married to Prince William
Pippa Middleton's iCloud account was hacked into, the British tabloid The Sun reported on Friday.
The hacker, using the pseudonym 'Crafty Cockney', reportedly stole about 3,000 pictures from Middleton's account. The images include Pippa at a wedding dress fitting and pictures of her fiancé James Matthews naked, The Sun reported. The couple is expected to get married next year.
The pictures also include photos of the Duchess of Cambridge Kate Middleton and Prince George and Princess Charlotte. Pippa is the younger sister of Kate. She was also the maid of honour at her sister's wedding to Prince William in 2011.
The British daily reported that someone had got in touch with them via WhatsApp and demanded $65,000 for the photos.
'This isnt [sic] an auction it will be a simple process of the highest bid,' The Sun reported the "cyber thief" as saying.
"On Friday, 23 September, police received a report concerning the alleged hacking of a personal iCloud account. Specialist officers are now investigating. No arrests have been made. Enquiries are ongoing," the Metropolitan police said in a statement:
