The expectant mum had a planned caesarean on Monday (29 September) and is delighted to have welcomed her first child with ex-fiancé Daniel Riley.
Confirming the news on Twitter today, Claire tweeted: "@DanReillyEpic We are thrilled to say our little boy came into the world on Monday at 1:58 pm. Thanks to all."
Meanwhile, Daniel has been thanking everyone for their congratulatory messages and well wishes via his own Twitter account.

With the birth pre-planned, Claire and Daniel have been looking forward to meeting their new arrival and just the day before Claire was due to have her C-section, the mum-to-be tweeted: "Less than 24 hrs till I meet my little man!" while Daniel joked he had had his "last lie in for a while".
Speaking on ITV1's Lorraine last month, Claire confirmed she and Daniel were expecting a boy as she couldn't resist finding out her baby's sex.
At that stage, Claire was debating on names for her son and did reveal she quite liked the name Gabriel - however, since the birth Claire and Daniel are yet to officially confirm their baby's name.
New mum Claire announced she was pregnant with her first child back in May when she was already five months gone.
Finally coming clean as her bump began to show, Claire admitted she wanted to keep her pregnancy private for at least three months due to suffering two miscarriages previously.
After thinking children would never be on the cards for her, Claire described falling pregnant with her baby as a "blessing".
And now he's arrived, she finally gets to embark on motherhood!
