Katie's fall comes after she said 2017 has been her 'worst year', and that she would like to have a drama-free 2018.
'I can't wait to put all of his drama behind me. It's been the worst year for me and I just want to put it behind me and start afresh,' she told Reveal magazine.
'I plan to get rid of Jordan, get rid of Katie Price and start as a new person. I'll keep the name but I'll be a brand new person. I'd like to have no dramas in 2018.'
