The Royal Baby boy weights 3.8 kilograms and was born at 4.24 pm. The boy's name will be announced in due course, the statement said but bookmakers make George the favorite name, followed by James.
As the birth was announced, a loud cheer went up and media gathered outside St. Mary's Hospital in west London, where William was born to the late Princess Diana in 1982.
Westminster City Council celebrated the announcement of the baby boy's birth with blue lighting in the fountains in Marble Arch and the Golden Jubilee bridge.
London mayor Boris Johnson said Trafalgar Square's famous fountains will be lit with blue lights for the next seven days in celebration of the royal birth.
London's Living Room at the top of City Hall will also use blue lighting over the next seven days to celebrate the royal birth.
In Sorrento, Italy, for example, free ice cream was given today to all the English people, just for the occasion.
Soon after the the Duke and Duchess of Cambridge leave the hospital, they will publish family photos, with the baby. You can check out the photos of previous royal babies in here.
Congrats to the royal couple!
