Pippa Middleton has chosen a name for her newborn baby girl

One month after welcoming their third child into the world, Pippa Middleton and her husband James Matthews have chosen a name for their baby girl.

The notoriously private couple have reportedly named their newborn daughter Rose.

According to sources, the 38-year-old is "so happy" and a "natural mama."

Just last month, Pippa debuted her baby bump at the Party at the Palace concert during Queen Elizabeth's Platinum Jubilee weekend.

Accompanied by her husband, brother James Middleton and sister-in-law Alizée Thévenet, she glowed in a bright green dress with shirred detailing along the bust and sleeves.

The new arrival is the sixth grandchild for Carole and Michael Middleton and a little cousin for Prince George, Princess Charlotte and Prince Louis.

Pippa and James first became parents in October 2018, when they welcomed Arthur Michael William.

They are also parents to one-year-old Grace Elizabeth Jane.

Pippa followed in the footsteps of her royal sister by giving birth in the Lindo Wing of St. Mary’s Hospital — the same place where Kate and Prince William welcomed all three of their children.

The couple met on holiday in the Caribbean in 2006. They dated briefly in 2012, before rekindling their relationship in 2015 and getting engaged in 2016.

Pippa and James tied the knot in May 2017 at St. Mark’s Church in Englefield.
