OTRC: Kate Middleton in labor, to give birth to her & Prince William's baby

Update: Kate, Duchess of Cambridge, has given birth to her and Prince William's first child, a baby boy. Find out more here.

Kate, Duchess of Cambridge, has gone into labor and is soon set to give birth to her and Prince William's first child, who is expected to become the heir to the British throne.

Kate, also known by her maiden name Kate Middleton, was taken to St. Mary's Hospital in central London on Monday morning.

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

"Things are progressing as normal," the couple's spokesman said.

She and Prince William, son of the late Princess Diana and grandson of Queen Elizabeth II, do not know the gender of the child, the Associated Press reported in June. Royal officials told the news wire that after the baby is born, a royal aide will leave the hospital with a signed bulletin carrying the Buckingham Palace letterhead, which will then be driven to the royal home and posted on an easel for the public to view.

An announcement will then be made on Twitter and details about the child's gender, weight and time of birth will be revealed.

Kate and William married in a televised ceremony in April 2011. Her pregnancy was announced on Monday, December 3, by St James's Palace, who added that the duchess was admitted that afternoon to a London hospital to treat Hyperemesis Gravidarum.
