England, meet your new Prince!
The Duke and Duchess of Cambridge just left St. Mary's Hospital in London, where their newborn baby boy made his big debut.
Kate Middleton and Prince William were beaming as they walked out with the 8 pound, 6 ounce boy, who was born at 4:24pm on Monday. Watch the video below:
After answering a few quick questions and posing for photos, William strapped the baby into his Britax Baby Safe Car Seat, which retails from around $100-$170.
The Duchess was wearing a baby blue Jenny Packham dress, which will surely sell out any moment now ... like everything else she wears usually does.
No name has been released yet, but the baby is now third in the British line of succession, behind William and his father Prince Charles ... meaning one day he will likely become the King of England.
"We are still working on a name, so we will have that as soon as we can," William told reporters.
Today, Charles and Camilla stopped by the hospital -- telling the crowd "You'll see in a minute" when asked about the baby.
Kate's parents Carole and Michael Middleton were seen at the hospital as well.
"We would like to thank the staff at the Lindo Wing and the whole hospital for the tremendous care the three of us have received," Will and Kate said in a statement on Tuesday. "We know it has been a very busy period for the hospital and we would like to thank everyone -- staff, patients, and visitors -- for the understanding during this time."
The hospital is the same one where the late Princess Diana gave birth to both Prince William and Prince Harry.
Fun fact: Both Princess Diana and Duchess Catherine wore polka dot dresses for their babies' debuts:
