According to reports, Beyoncé and her hubby went all out to ensure the jungle-themed bash was a huge success. And while the costs of putting on such an event have yet to be revealed, the cost of just a VIP tour at the sanctuary and botanical garden is around $240 - which means closing the entire venue is likely to be in the region of thousands of dollars.
Her parents' generosity meant that Blue saw in her second birthday surrounded by a host of exotic animals, including penguins, kangaroos and lemurs.
Later in the day, Blue, Beyoncé and Jay Z were seen enjoying lunch at Joey's restaurant in Miami, where they ordered two salads and two pizzas.
Pictures of the family at the eatery showed Blue looking adorable in a khaki and gold long-sleeved T-shirt with a tutu-style skirt, black socks and leopard-print trainers. The little girl managed a smile as she was carried by her superstar father, who opted for a grey sweatshirt, baggy black trousers and baseball cap.
Bey, meanwhile, showed off her slim figure in a pair of grey skinny jeans, black top and heavy gold necklace.
