Her Royal Highness has a moniker!

Prince William and Kate Middleton's newborn daughter has been named Princess Charlotte Elizabeth Diana, Kensington Palace announced on Monday. The choice of names are an ode to her grandfather, great grandmother, and late grandmother.

"The Duke and Duchess of Cambridge are delighted to announce that they have named their daughter Charlotte Elizabeth Diana. The baby will be known as Her Royal Highness Princess Charlotte of Cambridge," the palace said in a statement.

Charlotte is the feminine version of Charles, and is also Kate's sister Pippa's middle name. It's smart that they chose Diana as the middle name, because that would have been far too much pressure to live up to her legacy.

We wonder how George is adjusting to having a sibling?
