Prince William and the Duchess of Cambridge's second child's name pays homage to both sides of the family.
Prince William and the Duchess of Cambridge named their second child, who is fourth in line to the throne, as Charlotte Elizabeth Diana.
However, many congratulated the couple on choosing names that pay homage to both sides of the family.
Kate and Pippa are known as being very close. Pippa, who is now a writer for the Telegraph newspaper and author, served as Princess Kate's Maid of Honour when she married Prince William at Westminster Abbey on April 29, 2011, in London, England.
Queen Elizabeth is the eldest daughter of King George VI and Queen Elizabeth. She became Queen at the age of 25, and has reigned for more than five decades.
Princess Diana's death caused an outpouring of grief across the globe and, in recent days, British newspapers called for the Royals to pay respect to her by naming the new baby Diana.
"As the nation waits, why the Princess must be called Diana" said one headline on the front page of The Daily Telegraph newspaper this month.
"William's late mother was there in spirit, outside the hospital on Saturday, her oval sapphire and diamond engagement ring on the hand Kate used to adjust the sleeping baby's shawl," journalist Allison Pearson wrote in the article. William gave his fiancee that ring so that his mother, as he said, could be part of their wedding, and I'm sure her name will be passed on to his daughter in the same spirit of commemoration."
