It's a boy for Pippa Middleton, James Matthews!

Pippa Middleton, the youngest sister of the Duchess of Cambridge, Kate Middleton, welcomed her first child- a boy- with husband James Matthews.

The 35-year-old gave birth to her baby boy on Monday afternoon at St. Mary's Hospital in West London, the same hospital where Kate delivered her three children, Page Six reported.

In the past few months, Pippa has been snapped on multiple occasions running errands and attending a number of events despite her pregnancy. She even wrote about her pregnancy, wherein she stressed on the importance of stretching and meditation for to-be mothers.

Pippa and her husband, James, tied the knot in May last year. The couple was recently spotted on their babymoon at a luxurious resort in Tuscany, Italy.
