Royal Baby: U.K. Celebrates the Birth of New Prince

The prince is fifth in line for the throne.

The U.K. welcomed the arrival of the royal baby’s on St. George’s Day Monday with excitement all around the region.

The 8-pound, 7-ounce baby boy was born at 11.01 a.m. Prince William and Kate Middleton, the Duchess of Cambridge, greeted fans and well-wishers with their newborn outside St. Mary’s Hospital's just before 6 p.m.

They were then seen strapping the newborn into his car seat to take him home.

“Thrice the worry now,” Prince William remarked before getting into the vehicle. 

The baby, whose name is not yet known, is fifth in line to the English throne.

A large Union flag was raised over Buckingham Palace shortly after the announcement.

The Tower Bridge and Golden Jubilee Bridges were lit up in blue overnight as well.

Government buildings flew full mast British flags Tuesday morning to mark the exciting moment for the royal family.

The Royal Mint has even marked the arrival of the royal baby with a commemorative silver penny.

The baby's name is expected to be announced within 48 hours, according to reports.
