Kate Middleton and Prince William -- the proud new parents of an 8 pound, 6 ounce baby boy -- thanked London's St. Mary's Hospital Tuesday, as they're expected to bring their little royal bundle of joy home in the next 24 hours, and we've got all the details and more right here on Breaking Celebrity News.

The Duke and Duchess of Cambridge thanked the medical "for the tremendous care the three of us have received" in a statement, adding, "We know it has been a very busy period for the hospital and we would like to thank everyone - staff, patients and visitors - for their understanding during this time."

Kensington Palace Tuesday confirmed said "mother, son and father are all doing well this morning," as many well wishers outside the royal headquarters celebrated the birth, even as rains poured down on the area.

Celebrations also took place in New Zealand, Australia and Canada, as the baby will be third in line for England's throne, and subsequently, be a head of state in those countries and 12 others.
