It's official! The Duchess of Cambridge Kate Middleton has given birth to a bouncing baby boy after about nine months of major anticipation. The birth was confirmed in a letter posted in front of Buckingham Palace that read,

Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 4:24 PM today. Her Royal Highness and her child are both doing well.

Obviously, people all over the world were ecstatic at the eventual heir to the throne's birth...even pop stars! Celebs like Ellie Goulding, Little Mix and others took to Twitter to post their congratulations (and jokes!) for Will and Kate. Check out their kind words (and slight ribs) below:

Congrats once again to Will and Kate!
