Pharrell Williams tied the knot with longtime love Helen Lasichanh before celebrating in a lavish tartan-filled reception aboard a yacht on Saturday in Miami, Florida. 

The beautiful couple stepped away from tradition for the party both wearing different types of the patterned fabric.

Helen looked like a princess in a voluminous dark blue and green coat with a white gown peeking through underneath while the 40-year-old singer-songwriter opted for a red and green tartan tuxedo.

Many guests were also snapped in various types of plaid as the boat named 'Never Say Never' launched from Miami.

The couple then allegedly got married later that night at the Kampong National Tropical Botanical Gardens in Coconut Grove. 

Several famous friends accompanied the happy couple, according to Us Weekly.

'Usher and Busta Rhymes did a mini concert at the wedding,' a source said. 'It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to.'

Justin Timberlake and Robin Thicke were also rumoured to be performing at the fete.

Pharrell and Helen, who have a four-year-old son named Rocket, have kept their private life largely out of the public eye.
