When the only child of music's most powerful couple celebrates a birthday, you can be sure it'll be nothing but the best. Such is the case for the 2nd birthday of Blue Ivy Carter, Beyonce and Jay Z's daughter and precious bundle of joy.

Dailymail UK reports that the superstar parents closed down the Jungle Island sanctuary of Miami Zoo on Tuesday for Blue Ivy's 2nd birthday bash that was jungle-themed.

Park officials are keeping mum about the details and the total cost of the event but VIP tour tickets for the sanctuary and botanical garden is pegged at approximately $240 per person. It's pretty safe to say Blue Ivy's birthday was one to remember.

TMZ reported that Blue Ivy spent the day with lemurs, orangutans, kangaroos and penguins at Jungle Island - a wildlife park and botanical garden in Miami.

As an added treat, being Blue Ivy means you don't have to do with the classic lullabys, you have them made for you by your Uncle, no other than Kanye West. 

The tiny tot turned 2 last January 7 and sources say that on top of the exotic bonanza of a party, Kanye West wrote a lullaby especially for the young lady, reveals Dailystar UK.

Wanting to do something personal for his best friend's baby, the age-appropriate lullaby talks about the powerful future and friendship of Blue Ivy and North "Nori" West, 7-months, will have in the future.

 "It's really catchy and slow. Rather than the usual sweet dreams-themed lullaby songs, Kanye raps about how Blue Ivy and Nori will be mega powerful when they're older. It also mentions how him and Jay-Z will work hard to make sure their girls have an easier path than they did."

The song, however, will not be released and will be just for Blue. "He hopes it'll send her off to sleep at night," says insiders.
