Pippa Middleton gave birth on Monday afternoon to her first baby, a boy, who added another grandson to the Middleton clan and a cousin brother cousin to Prince George, Princess Charlotte and little Prince Louis of Cambridge.

The birth was confirmed on Tuesday morning by Middleton's representative in London, Jo Milloy.

"He was born on Monday (October 15) at 1:58 p.m., weighing 8 (pounds) and 9 (ounces)," the representative told USA TODAY. "Everyone is delighted and mother and baby are fine".

The younger sister of former Kate Middleton, now Duchess Kate of Cambridge, Pippa, 35, had her baby at St. Mary's Hospital in London (where the real children were born), with her husband James Matthews at his side.

Matthews was seen by the paparazzi who entered the Cute Maternity Wing at the hospital the same day that Britain and the rest of the world absorbed the news that Prince Harry and Duchess Meghan of Sussex await their first baby in the spring.

The couple was last seen in public at Friday's wedding of Princess Eugenia of York and Jack Brooksbank, at Windsor Castle; Pippa was very pregnant and was wearing a long dark green dress.

This is Pippa's first child and his parents' fourth grandchild, Carole and Michael Middleton, who also have a son, James, 31, who is not married.

For the small members of Cambridge royalty, including the future King Prince George, now 5 years old, the new baby is his first cousin; So far, they have four second cousins, the sons of their father, Prince William, cousins, Peter Phillips and Zara Phillips Tyndall.

The real children can also expect a new cousin soon: Uncle Prince Harry, 34, and Duchess Meghan, 37, announced Monday that they are expecting their first child in the spring.

The baby also has a cousin from his father: Theodore Fredrick Michael, who was born on September 5, son of James' television star brother, Spencer Matthews and his wife Vogue Williams.

With the baby Prince Louis, who was born in April, he makes three related babies in the Windsor, Middleton and Matthews families, and a fourth on the way.

Pippa and Matthews, 43, a London financial millionaire, were married in May 2017 in a luxurious semi-royal wedding that featured the presence of George and Charlotte, now 3 years old, as protagonist and maid of honor.

Then the couple embarked on their honeymoon in Australia.

The news of Pippa's pregnancy was only confirmed in June, although she was very suspicious when she attended the wedding of Harry and Meghan a month earlier.

Pippa herself revealed her condition in her monthly column of exercises for the magazine Waitrose Weekend, in an article about exercise during pregnancy. (Pippa is as healthy and sporty as her sister).

But she has had more luck than her sister, who suffered crippling attacks of acute morning sickness in the early stages of her three pregnancies. Among other things, that forced Kensington Palace to announce their pregnancies earlier than usual.

"I was lucky to pass the 12-week test without morning sickness," Pippa wrote. "That meant I could continue (normal) and continue my sports."

By August, she was in her third trimester, according to her last column, about how swimming is her favorite exercise routine as she prepares for delivery.

"I would say with confidence that it seems to me that it has been the most pleasurable and rewarding form of exercise since I discovered that I was waiting," he wrote.

The Matthews live in an expensive mansion in London's Chelsea neighborhood, where Pippa has lately maintained a more discreet profile than immediately after her sister's royal wedding in 2011, when she rose to fame as a bridesmaid with a curvy butt .

There has only been one cloud in the lovely lives of Pippa and Matthews: his father, David Matthews, 74, was arrested by French police in March and charged with the rape of a minor in the late 1990s, an indictment that he has denied. The case is still under investigation.
