Kensington Palace has announced that Kate Middleton was in early labor with her third child and shortly after she gave birth to a baby boy weighing 8 lbs., 7 oz.

Moments ago, Duke and Duchess of Cambridge took him outside for a photo op on the clinic’s steps and new mum Kate looked chic in a red dress with a lace collar.

Before the little prince was formally introduced, William left the hospital to pick up his elder children Prince George and Princess Charlotte.
