Amy, 64, has been diagnosed with Idiopathic Pulmonary Fibrosis just days after Katie revealed her third marriage to Kieran Hayler is over last week.
Revealing her devastating news about her mum to fans on Saturday, Katie vowed she would remain ‘upbeat’ as she explained the average life expectancy is three to five years.
Speaking to The Sun, Katie said: ‘She’s got something wrong with her lungs and she’s been told she hasn’t got very long to live.
‘She’s on tablets… at last I’m making her laugh. Whatever is happening we’ve got to be upbeat about it.’Katie later thanked her fans for their support on Twitter, asking them to join her family in supporting The British Lung Foundation.
She wrote: ‘Just to clarify for all of you reading. My mum has been diagnosed with a lung disease called Idiopathic pulmonary fibrosis (IPF) there is unfortunately no known cure for this.
‘As a shock to us all, Me and my family are proud to be supporting the British lung foundation to help support awareness and raising funds for research of IPF. With this we can help in other diagnosis and create awareness for people with IPF.
‘The condition has an average life expectancy of 3-5 years. There are two known pills which if they work can slow things down. My mum is a fighter she is working out every day, going to work and living life to the full please help us in supporting The British Lung foundation so we can make a difference.’
Her mum also revealed how positive Katie had remained during the test stages, adding: ‘During the tests, which were really quite personal, she was making so many funny comments that both myself and the specialist were in fits of laughter.’
Katie announced her marriage to Kieran is over last week, claiming he has been sleeping with their nanny for six months.
The mum-of-five also revealed how Kieran had told her they’d had sex all over their house, including the children’s bathroom.
