See Harry's joy in this touching video!
But while classic names lead the stakes, many royal experts believe modern royal couple Harry and Meghan will opt for a more unusual title for their little bundle of joy.
Many commentators believe the young royals could honour Harry's late mother Diana by naming their son her family name, Spencer.
Other non-traditional possibilities include the name Grey, which former Suits actress Meghan once proclaimed to be her favourite boy's name on her now defunct lifestyle blog The Tig.
Prince Harry and Meghan announced the birth of their first child via their official Instagram account Sussex Royal with a sweet post early Tuesday morning.
"We are pleased to announce that Their Royal Highnesses The Duke and Duchess of Sussex welcomed their firstborn child in the early morning on May 6th, 2019.
"Their Royal Highnesses’ son weighs 7lbs. 3oz.
"The Duchess and baby are both healthy and well, and the couple thank members of the public for their shared excitement and support during this very special time in their lives.
"More details will be shared in the forthcoming days."
