Pharrell Williams has married Helen Lasichanh.

The producer-and-musician tied the knot with his supermodel fiancee yesterday (12.10.13) at a star-studded ceremony in Florida.

Many famous friends attended the bash in Miami, including rappers Busta Rhymes and Usher who performed a ''mini concert'' for the guests.

An insider told ''Usher and Busta Rhymes did a mini concert at the wedding.

''It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to.''

Another guest revealed the pair were even set to treat those at the wedding to renditions of some of Pharrell's own hits.

They added: ''Of course they're playing some of [his] hits tonight.''

The couple got engaged last summer, and together have a four-year-old son Rocket.

The 'Get Lucky' hitmaker has spoken recently of his immense pride at their child, describing him as the ''best'' collaboration and insisting his friendship with Helen makes ''every night'' feel ''like a sleepover''.

He previously said: ''[He's the] best song that I've ever co-written ... It's awesome.

''I can't tell anyone what to do. I can't give anyone relationship advice. But the bestie thing is awesome. Every night is like a sleepover.''
