The Grammy-nominated singer planned a star-studded surprise party for her hubby and invited 50 of his closest pals, including Diddy, Kate Hudson, A-Rod, Kanye West and Alicia Keys.
DJ Cassidy spun tunes at the bash held at the Casa de Campo resort in the Dominican Republic. The party, which had a 1940s theme, included a fireworks show and two dance floors.
At the fete, Jay-Z and Keys sang an impromptu version of their hit song, "Empire State of Mind," and West gave a toast to his friend, the birthday boy.
