Royal Baby Watchers Just Received Their First Clue About When Kate Middleton Will Have Her Baby

A spring royal baby could be welcomed into the world any day now.

The hospital where Kate Middleton will give birth just added a fresh coat of paint to their outdoor railing.

According to People, when a fresh coat of paint is added, it means that a royal baby will soon be born.

With Kate's due date of April 23 nearing, baby No. 3 could come sooner than expected.

The couple were both photographed holding their first and second child, Prince George and Princess Charlotte, on the steps next to the railing.

We can't wait to meet the new royal baby!
