Michelle Heaton is pregnant.

The Liberty X singer took to her Twitter account today (19.08.13) to announce she is expecting her second kid with husband Hugh Hanley, and she can't wait for their 20-month-old daughter Faith to have a new brother or sister.

She revealed: ''Myself and @hughhanley are thrilled we are expecting a mini Michelle or Hugh.

''..this is a very exciting time for us after everything that's happened.. Thank you as always for your love & support! Whoop whoop! Xxxx

''Awww thank u for your well wishes. Yes, faith is gonna be an amazing big sister. She's already kissing my stomach. Have a great day all! X (sic)''

The 33-year-old star's joy comes after she had a double mastectomy last year after she was found to be carrying the BRCA2 cancer gene, meaning she had an 85 per cent chance of developing breast cancer and 40 per cent chance of developing ovarian cancer.

Michelle previously said she wanted to have more children, but if she wasn't able to have more kids because of her medical problems then she was content with her ''healthy, beautiful baby'' Faith.

She said: ''There's a lot to consider about ovary removal. It starts the menopause, which would obviously mean I couldn't have any more children.

''I have one healthy, beautiful baby, and if I never have another I know I'm lucky to have her - but I would love more if possible, so that will be a big decision.''
