The 40-year-old former glamour model agreed to take part in a 28-day programme at The Priory this week after she was diagnosed with post- traumatic stress disorder, but her treatment has already been interrupted as she temporally stopped her plan on Friday (28.09.18) in order to attend her manicurist Abigail Scott's big day.

A source told the Daily Mirror newspaper: "Katie was on top form and was having a great time. She didn't seem like a woman who was in rehab."

However, a representative has told the MailOnline that Katie had told the team at The Priory before she started the programme that she had a wedding coming up and they agreed to give her the time off to attend.

They said in a statement to the publication: "The priory were aware Kate had a wedding to attend for her very close friend before she took the treatment. She went to the church and left the wedding for 4pm. Katie was driving. Her treatment resumes as usual on Monday."

Katie - who doesn't stay over night at the facility - agreed to enter rehab after her family urged her to seek help.

Her mother Amy - who has a terminal lung condition - said recently: "Kate has been her own worst enemy and behaved like an idiot at times but she has been tearing herself apart for years.

"To see what Katie is going through and how she has been treated hurts me and my family. No mum or dad wants to see their child treated like this, watch as they crumble, and feel powerless to help. It's unbearable.

"She is constantly judged on her kids, her home, work, financial situation, the way she looks, how she dresses and what she does. No person can take this kind of pressure and not succumb to it. Of course she has put herself in the public eye but she has been dealing with endless attack as well as my illness."

Katie - who has children Harvey, 16, with Dwight Yorke, Junior, 13, and Princess, 11, with ex- husband Peter Andre, and Jett, five, and four-year-old Bunny with estranged spouse Kieran Hayler - has been put on a curfew, has had her phone confiscated and been banned from social media.
