Ambam, the western lowland gorilla, became a viral web sensation when a video of him shaking his bum like Nicki Minaj was viewed more than 6 million times.
The big ape, who weighs in at a whopping 500lbs, was treated to a cake made by a local baker – containing yoghurt, coconut, grapes, bananas and potatoes.
Ambam, who was born at Port Lympne Reserve in Ashford, Kent, has become a star attraction, because he prefers to walk upright like a human rather than on his knuckles.
He loved his birthday cake so much he refused to share it with any of the other gorillas, and was seen grabbing huge handfuls of it before running away.
Baker Lynsey Mclean, owner of M&B Bakehouse, presented the gluten and sugar-free cake to him on Tuesday.
