BBC newsreader Kate and her husband Mike Heron welcomed their son last week and have called their "little ray of sunshine" Wilbur.
Announcing his birth on Twitter yesterday, she said: "Gorgeous morning all - Introducing #Wilbur our little ray of sunshine x."
Kate has spoken openly in the past about her struggles to conceive a second child, making Wilbur's arrival all the more special for the couple.
The couple already have a daughter, Clemency, and went through four rounds of IVF and suffered two miscarriages before she fell pregnant with Wilbur.
Speaking on ITV1's Lorraine earlier this year, Kate admitted that it happened naturally after she and Mike had resigned themselves to the thought that they would never have a second child.
