On Monday, Pippa Middleton and husband James Matthews welcomed a baby boy.
Extra reports the baby weighed 8 lbs. 9 oz.
Her rep told People magazine, ?Everyone is delighted and mother and baby are doing well.?
The 35-year-old gave birth in the Lindo Wing of St. Mary?s Hospital.
It's the same location where older sister Kate Middleton and Prince William welcomed their three children.
Just days before the baby?s arrival, Pippa showed off her baby bump at Princess Eugenie?s wedding.
