Happy birthday to our favorite girl, who makes the game look easy, Beyonce!

We hear Jay did it big for his wife, by celebrating at a New York eatery called The Darby, where the couple were joined by Kayne West, P Diddy, Serena Williams and Alicia Keys.

An insider told the New York Post newspaper: “Jay brought a six-layer cake out for Beyonce, they were really affectionate. Cassidy played Stevie Wonder’s ‘Happy Birthday’. The party went on until 6 am. Jay brought a six-layer cake out for B, they were really affectionate. Cassidy played Stevie Wonder’s ‘Happy Birthday.'”

We hear Lady Gaga gifted Bey with a diamond-encrusted whip and matching lingerie set.
