Pippa Middleton and husband James Matthews have named their son Arthur.
Revealed in the UK's Mail On Sunday, the Duchess of Cambrige's sister, 35, welcomed her baby boy weighing 8lb and 9oz at the private Lindo Wing, at St Mary's Hospital, Paddington, last month but at the time his name
was kept under wraps.
The couple have also given their baby boy the middle names Michael and William.
The name Michael is a touching tribute to Pippa's father and her husband's younger brother who died while climbing Mount Everest in 1999.
Michael Matthews went missing on the mountain's infamous Death Zone while he was trying to become the youngest Briton to climb the world's highest peak.
