Duchess Kate is an aunt! Pippa Middleton, the younger sister of Catherine, Duchess of Cambridge, gave birth to her first child with husband James Matthews on Monday, October 15, People reports. The pair welcomed a baby boy at 1:58pm local time.

“Everyone is delighted and mother and baby are doing well,” Middleton’s rep told People, which reports that the new arrival weighed in at 8 pounds, 9 ounces.

Earlier on Monday, Middleton was spotted arriving at the Lindo Wing of St. Mary’s Hospital in London, the same place where Kate gave birth to her three children, five-year-old Prince George, three-year-old Princess Charlotte, and five-month-old Prince Louis.

Middleton, who married Matthews in May 2017, was first reported to be pregnant in April. She confirmed the reports in June, telling Waitrose magazine that she was lucky not to suffer any morning sickness, let alone hyperemesis gravidarum, which struck Duchess Kate during all three of her pregnancies.

News of the birth comes just hours after Prince Harry and Meghan Markle revealed that they are expecting their first child next spring, and less than a week following the wedding of Princess Eugenie, which Middleton attended with Matthews on Friday, October 12.
