The 37-year-old TV presenter allegedly appears in pictures with husband Patrick Kielty, where the two are seen sharing intimate moments, reported the Daily Mirror.
The incident draws resemblance to the infamous scandal, in which celebrities like Jennifer Lawrence, Kim Kardashian, among others had their naked photos leaked all over the internet.
Deeley's have been posted on a number of sites and although she has not confirmed they are of her, she was named on the hacker's list of victims.
It is thought the photographs have been on the internet for more than a week but have only just circulated this weekend on other websites.
