Pharrell Williams is one lucky guy! The Grammy award-winning record producer tied the knot with his girlfriend model Helen Lasichanh on Saturday, Oct. 12, Us Weekly can confirm. The "Get Lucky" singer and his new bride exchanged vows in Miami, Fla.

The newlyweds were feted by several famous pals, including Usher and Busta Rhymes. "Usher and Busta Rhymes did a mini concert at the wedding," a source revealed to Us. "It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to."
