Yesterday afternoon (4 August), Katie gave birth to her fifth child - a little girl - reportedly 11 days before her planned C-section. The baby's name has not yet been revealed.
Announcing the news on Twitter, Katie's rep said: "[We] can confirm that our client @MissKatiePrice has given birth to a baby girl this afternoon - no more details will be given at present."
Each Tuesday, Katie appears alongside Mark Dolan for a three-hour show on Fubar Radio, although she was understandably not on the airwaves today.
In a special message, Mark told listeners who had tuned in: "I would like to wish Katie Price, my fabulous co-host, our very best wishes for arrival of a brand new little girl.
"We're delighted. It's the dawn of a new era. This is just what the world needs, a little Katie Price running around causing havoc at nursery. Well done, you've done it again!"
Katie has had a tough time recently. Just days after discovering she was unexpectedly six months pregnant, Katie announced that she was to divorce her third husband, Kieran Hayler, for cheating with her best friend, Jane Pountney.
Since then, Katie has accused Kieran of also sleeping with a second woman behind her back, and revealed that she made him take a lie detector test.
However, both Kieran and Jane have apologised for their behaviour and Katie has decided to stand by her man - for now.
Explaining that Kieran is receiving therapy for a sex addiction, Katie recently said on her Fubar Radio show that she would not be breaking her wedding vows.
Katie did confirm though that she will divorce Kieran if he ever cheats on her again.
"If it happened again, absolutely he would be gone," she said.
Let's hope Mark is right, and that Katie and Kieran's baby girl really does signify the dawn of a new era for the couple.
