The TV star has also previously praised Martyn for helping her overcome breast cancer in 2008.
Christina – who had to undergo a double mastectomy after being diagnosed with the disease – said: ‘I have a small but mighty support system and Martyn has really been an incredible part of my life. ‘Without him, I don’t know if I could’ve gone through any of it. He came around at a time when there was a lot of loss in my life on many levels, so he’s been a really incredible help.’
