Kate Middleton's sister Pippa and her husband James Matthews celebrate baby boy's birth
Pippa Middleton and her husband, James Matthews, welcomed their first child, a baby boy on Monday, she gave birth in the Lindo Wing at St. Mary’s Hospital in London, the same hospital where her sister, Kate Middleton, gave birth to all three of her children, including Prince Louis in April.
The news comes just a day after Prince Harry and Meghan Markle revealed they are expecting a baby.
A spokeswoman for Pippa and her husband James Matthews said, the baby was born on Monday at 13:58 BST weighing 8lb 9oz,
"Everyone is delighted and mother and baby are doing well," she added.
A Kensington Palace spokesman said Prince William and Kate Middleton were "thrilled" for the couple.
Pippa and James last major public outing was at the wedding of Princess Eugenie and Jack Brooksbank on Friday.
Pippa Middleton announced her pregnancy in June in her fitness column for Waitrose Weekend magazine.
The couple were married in May last year in a ceremony attended by royals and A-list celebrities.
Pippa told readers she had passed through the first trimester without experiencing the severe morning sickness her older sister Kate Middleton had with her three pregnancies.
"I was lucky to pass the 12-week scan without suffering from morning sickness," she said.
"That meant I was able to carry on as normal and continue my sports."
In a recent column for the magazine she wrote: "As the final month nears and the bump grows prouder each day, movement is certainly getting more awkward.
"As a result, one of the biggest changes is that my lower body has tightened up."
