Up all night! Alicia Keys (I just love you) and Swizz Beatz at Pharrell's curious SpongeBob SquarePants themed 41st birthday(Photos)

She's a legend in the music industry just like Pharrell Williams, but even Grammy Award winners are allowed to get childish sometimes.
And Alicia Keys did just that, as she and her husband Swizz Beatz showed up to help their oversized-hat loving friend celebrate his SpongeBob SquarePants themed 41st birthday party on Friday night.
The 33-year-old songstress looked stunning in royal blue as she joined the array of music industry favourites in New York City.
More after the cut.

 The Wall Street venue, Cipriani's had been transformed into the cartoon character's famous underwater home Bikini Bottom - and he was in his element.
The birthday boy was kitted out in a brand new park ranger hat, this time in dark green.
He put on a bright smile as he posed between Alicia and Swizz for a birthday snap.

Also in attendance was Nicky Hilton, who is apparently also friends with the illustrious hitmaker, and controversial photographer Terry Richardson.
Alicia and Pharrell surely got to know each other quite well recently in the course of doing a track together, entitled It's On Again, which the duo did along with Kendrick Lamar for the upcoming The Amazing Spider-Man 2 soundtrack.
