Pippa Middleton has welcomed a baby boy!
The sister of Kate Middleton gave birth to her first child with husband James Matthews on Monday afternoon at the Lindo Wing in West London — the same place Kate welcomed her three children.
The boy, whose name has not been released, weighed 8 pounds, 9 ounces at birth.
Pippa documented her pregnancy in a column for the U.K.'s Waitrose Weekend, writing about her exercise regimen.
"I was lucky to pass the 12-week scan without suffering from morning sickness," Pippa wrote. "That meant I was able to carry on as normal and continue most of my sports..."
Pippa and Matthews wed in May 2017.
