Pharrell Williams married his longtime girlfriend, model Helen Lasichanh, in Miami on Saturday, a source tells Us Weekly.

The guest list included some of the singer-songwriter-producer’s famous friends, including Usher and Busta Rhymes. The source says Usher and Busta “did a mini-concert at the wedding,” adding, “It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to.”

Another source tells Us some of Williams’ hits were also played that night.

Williams, 40, and Lasichanh have a four-year-old son, Rocket.
