The mother-of-four discovered a collection of intimate pictures featuring a former lover had been stolen from her home, and the 35-year-old was then blackmailed.
Taking to Twitter this morning, Katie- also known as Jordan- wrote:
‘Somebody has been arrested and charged about blackmailing to use these stolen pictures so a step closer to who stole them’.
However the new mother, who gave birth to son Jett with third husband Kieran Hayler last month, confirmed that she had not been worried over the incident.
‘For the record im NOT worried about any sex pictures and it's NOT affecting my relationship, I'm sure ...... would be worried’.
The blank space appears to refer to the other person pictured in the snaps, whose identity has not been revealed.
Katie is also mother to 11-year-old Harvey from her relationship with Dwight Yorke, as well as Junior, 8, and Princess, 6 with ex husband Peter Andre.
The model gave birth to Jett 8 weeks early last month, during a European holiday with her husband of 8 months.
The couple were then plagued by Twitter trolls posing as Jett, accusing him of not being the father, to which he responded:
‘@Mr_JR_Price can you please take my sons name off of here. Have some respect.’
The couple have kept a low profile since their return to the UK.
