Kate Middleton, Prince William Royal Baby Boy: Celebrities Who Share July 22 Birthday, Cancer Astrological Sign: Selena Gomez, Alex Trebek, David Spade, More! [PHOTOS]

Kate Middleton gave birth to Prince William's royal baby boy on Monday, July 22, 2013. His Royal Highness was born at 4:54 GMT - just minutes before the cutoff line for the astrological sign of Cancer (just like his dad!). Several celebs share the same birthday as the new Prince of Cambridge, including Selena Gomez, Alex Trebek, and David Spade. Check out more July 22 b-days below!

According to Hollywood Life, astrology experts believe that the new Royal will show specific characteristics because he was born just before the Cancer cutoff line. “If the baby is born before 4:54 p.m. GMT he will be a Cancer - like father William - but his moon will be in Capricorn, which is the same star-sign as mother Kate,” The Association of Professional Astrologers expert Deike Begg told Mail Online. "This means the baby will share a lot of the parents’ personality traits. As a Cancer, the child will be very family oriented like its parents and sensitive. Cancers often appear strong on the outside but are very soft on the inside. But with a Capricorn moon it would also be aware of its responsibilities and dependable."
