As the Duke and Duchess of Cambridge delight in the arrival of their baby bundle of joy, Drusillas Park in East Sussex is also celebrating a new prince... of Lemurland.
Keepers at the award-winning zoo have confirmed that their black lemur born in April is male.
The gender of a black lemur becomes evident over time due to the strong sexual dimorphism in colour within this species.
Males are all black with striking orange eyes, whereas females are brown with long whitish ear tufts.
The Duke and Duchess of Cambridge proudly showed the world their baby son, a future king, before taking him home tonight.
We look back at Kate's journey since early December 2012 when it became public knowledge that a royal baby was on its way.
