This Morning' presenter Holly Willoughby, 33, and her husband Daniel Baldwin welcomed their third child into the world today and have named him Chester William.
Taking to her Twitter account, Holly gushed: "I'm sooo happy to tell you all - we've just had a baby boy! Chester William Baldwin made a grand entrance at 8lbs 12. He's just perfect. (sic)."
The couple, who got married in 2007, announced they were expecting another child in March on her blog.
She wrote at the time: "Surprise Surprise (and it was a surprise!!)
I'm really happy and excited to tell you that Dan and I are expecting baby number 3!! (sic)."
The announcement came just a few days after rumours began to swirl when Holly was pictured leaving the 'Celebrity Juice' studio hiding her stomach with an over-sized coat and long pink scarf.
However, the news didn't come as a complete shock as the blonde beauty said last year that she was "perennially broody" for another baby.
