It's a princess!

The palace also tweeted the announcement, a lean towards modern baby announcing.
The new princess is automatically fourth in line to the British throne, following grandpa Prince Charles, father Prince William, and big brother Prince George of Cambridge -- jumping uncle Prince Harry in the succession.
Also, the new princess will not be overtaken in the line of succession by any future younger brothers. New rules that came in March noted male bias was removed from the succession rules. The newborn will also be known the Princess of Cambridge after a Letter Patent was issued by the Queen.
It stated, "All the children of the eldest son of the Prince of Wales should have and enjoy the style, title and attribute of royal highness with the titular dignity of prince or princess prefixed to their Christian names or with such other titles of honour."
The princess will also be able to marry a Roman Catholic without losing her place in line to the throne.

Kate was admitted to St. Mary's at 6 a.m. Saturday in London, being in "the early stages of labor." She reportedly traveled by car straight from Kensington Palace to the hospital's private Lindo Wing, same one where George, William and Harry were all born too.
Dr. Alan Farthing (Queen Elizabeth II's surgeon-gynecologist) and Dr. Guy Thorpe-Beeston (obstetrician specializing in high-risk pregnancies) were set as the ones to look over the arrival of the new heir. Both helped deliver newborn George into the world nearly two years ago.
A team of midwives were also present for the princess' delivery.
A month ago, Prince William was eagerly awaiting his newest royal babe, saying he "couldn't wait another minute" for her to be born.
The Duchess may plan a longer maternity leave from her official duties than she took when George arrived, as she's rumored to want to spend more quality time with both the children.
William will take two weeks off from his new post training as an air ambulance helicopter pilot, according to the palace.
Congratulations to the royal couple on their little princess!
