It's only a matter of time before the royal baby arrives!

Kate Middleton is officially in labor, according to a Palace rep, after checking into the hospital early Monday morning.

"Hey Royal Highness The Duchess of Cambridge has been admitted this morning to St. Mary's Hospital, Paddington, London in the early stages of labour," they said in a statement. "The Duchess traveled by car from Kensington Palace to the Lindo Wing at St. Mary's Hospital with the Duke of Cambridge."

Kate and William returned to London on Friday after vacationing at Kate's family's home in the country.

As soon as the royal baby is born, an official document with the baby's sex and birth weight will be displayed on an easel outside of the hospital.

Do you think Kate's having a boy or a girl?
