THEY may not have blue blood in their veins but these three new arrivals to Croydon are all princes in their mothers' eyes.
Testosterone was in the air at Croydon University Hospital on Monday, just as it was in the Lindon Wing of St Mary's Hospital on the same day when the Duchess of Cambridge gave birth to the third in line to the throne, George Alexander Louis.
For the proud parents of three boys sharing the new prince's birthday, the Royal connection was the icing on the cake.
First-time mother Jamira Semambo, 23, of South Norwood, cuddled baby Emre as she spoke to the Advertiser.
She said: "It's a really nice feeling to have my baby boy born on the same day as a potential King of England.
"I wish Kate the best of luck. We both have a challenging, but extremely exciting time ahead of us.
Ms Semambo went on to say: "I knew that they were going to be born on the same day. I had my scan at the same time that Kate had hers so it was no surprise that it might happen to me, but I am delighted that it did."
Doris Shonowo, 36, of Thornton Heath, said it was "a privilege" for her son Miciah to be born on the same day as the new Royal.
She said: "Who knows? Maybe they could grow up to be friends."
Another new mother on the ward, Doris Akote, 38, of Thornton Heath, gave birth to baby Dre.
She said: "I hope that their baby does grow up to be king and I wish them the best of luck in raising him".
Fourteen other babies were born in the new ward of Croydon's former Mayday hospital on the same day and will share their birthday with the new prince.
