Earlier today, Michelle and her husband Hugh welcomed the arrival of their baby boy and announced the news on Twitter.
This came just 10 hours after Michelle had told her followers that she was "bored" of waiting to go into labour!
Big Reunion star Michelle, who is also mum to two-year-old daughter Faith, has now thanked her followers after being inundated with tweets of congratulations.
The Liberty X singer said: "Thank you all so much for your well wishes.. Mine & @hughhanley little boy is snuggled into us and we are the happiness parents ever.. Xx."

Michelle and Hugh have not yet announced the name of their little boy.
Their son's arrival is doubly special for the couple, as Michelle was diagnosed with having the BRCA2 faulty gene in 2012. In November of the same year, Michelle underwent a double mastectomy, as the gene means she has a high chance of developing breast and ovarian cancer.
Michelle has decided to have her ovaries removed, meaning this will be her last baby, and told Reveal in December: "No matter how daunting having my ovaries out is - and it is - it's necessary."
She added: "I'd be risking my life if I had another baby."
