Katie Price poses with her casts before major foot surgery

She's preparing for major surgery on her two broken feet on Friday.

A source told The Sun: 'Katie's doctors told her she had to stay lying down on her back to stop her feet swelling up in the heat. 

'She's terrified about the surgery tomorrow - but she's listening to all the doctor's advice.'

The source added that Katie was 'devastated' about the medical advice as it meant she couldn't celebrate her youngest son Jett's birthday properly. 

However it is thought that the mother-of-five has told him that she will make it up to him with another party after the operation.
