She said: “James and Pippa have had a baby boy.
“He was born Monday 15th October at 1.58pm, weighing 8lb and 9oz. Everyone is delighted and mother and baby are doing well.”
Pippa has been outspoken about the fact she continued exercising throughout her pregnancy – turning to meditation and swimming among other things.
She was also often seen cycling with her baby bump in London and so it will come as little surprise to royal watchers to see her out and about with her new bundle of fun.
Pippa dressed in a chic grey leather jacket and wore sunglasses as she stepped out on Oct. 24.
She pushed her newborn baby in a blue pram and wore comfortable white sneakers as she strolled along the pavement in Kensington, London.
The baby – whose name has not yet been announced – is the first child of Pippa and James Matthews who married last year.
