Even at the age of 41, Pharrell still has a thing for SpongeBob SquarePants.
After rocking SpongeBob SquarePants onesie at the Nickelodeon Kids' Choice Awards last week, the "Happy" crooner took his love for the animated character up a notch with a SpongeBob SquarePants themed birthday bash at Bikini Bottom at Cipriani Wall Street in New York City.
His wife Helen Lasichanh was by his side as he rang in his big 4-1, along with Alicia Keys, Swizz Beatz, Russell Simmons, Angela Simmons, Chanel Iman, Nicky Hilton Rothschild, Josh Lucas and Soledad O' Brien, among others. Q-Tip was also there, serving as the DJ for the evening.
And, yes, Pharrell was wearing The Hat (the green version).
