She wrote: “Well hello world, just surfaced to let you know that we now have a daughter!
“Born on Monday morning just as @BBCBreakfast was wrapping up.
“We’re all fine and dandy. Just getting used to the eau de sick/poo I am now regularly wearing. #babylife.”
The new mum was pictured out with her daughter for the first time last week, after returning to the BBC Breakfast sofa as a guest.
