Not many 41-year-olds can get away with a Spongebob Squarepants-themed party, but luckily Pharrell Williams is not like other 41-year-olds.

The music extraordinaire celebrated his birthday by transforming New York City's Cipriani into Bikini Bottom for a bash starring Nickelodeon's "pineapple under the sea" resident.

Attended by the likes of "It's On Again" collaborator Alicia Keys, Swizz Beatz, Russell Simmons and Alexander Wang, the party boasted DJ’ing by Q-Tip, elaborate decor and appearances from the cartoons of the hour.
