The arrival of the royal baby will be marked in tonight's episode of EastEnders after show bosses ordered some last-minute filming to reflect the birth.
A scene showing Dot Cotton (June Brown) and Abi Branning (Lorna Fitzgerald) discussing the happy news was filmed last night and will feature in the BBC soap tonight.
A spokeswoman for the show said: "This is such a momentous occasion for the Royal family, the country and of course the residents of Walford that we felt it should be marked in EastEnders history."
The Duke and Duchess of Cambridge spent last night with their son at St Mary's Hospital in London.
This is not the first time the show has celebrated historical events. It has previously made references to the couple's wedding and has honoured sporting achievements including Olympic success in 2012 and Andy Murray's Wimbledon win.
