The star also discussed her tough journey to motherhood, and admitted she had given up on ever having children before her whirlwind romance with Adrian.

The star also made the heartbreaking admission that she had endured a miscarriage before falling pregnant with her son.
She said: 'I read there's only a five per cent chance for a woman to get pregnant per month and the risk of miscarriage increases and sadly I went through that but it taught me that I could get pregnant.
'I got to 42 thinking it would never happen. I have had ovarian cysts, but you add everything up and it took my mum seven years to have me in the 70s. I was classed as a miracle baby.
'I thought I will throw myself into work, and I found myself single and 40 thinking that time is gone, people would ask how I was and if I was okay with that and I would say I was career minded but then I met Adrian.
'We took our relationship very slowly to begin with, and we talked about having kids but I said that I might not be able to have them but he said "that's okay we can adopt"'
