Pharrell Williams is officially off the market! The 40-year-old producer tied the knot with his "bestie" Helen Lasichanh in Miami on Saturday (Oct. 12).

According to Us Weekly, the couple exchanged vows at the Kampong National Tropical Botanical Gardens in Coconut Grove. Among the guests in attendance included Busta Rhymes and Usher.

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

After the wedding, Williams and Lasichanh held a lavish reception on a yacht called "Never Say Never" with several guests, reports the U.K.'s Daily Mail.

Interestingly, the beautiful couple wore different types of patterned fabrics for their outfits.

Skateboard P donned a red-and-green plaid tartan tuxedo while Lasichanh wore a puffy dark navy-and-green coat with a white gown underneath.

Photographer Terry Richardson, who has photographed Williams for fashion shoots and magazine covers, was also in attendance, possibly capturing the whole reception with his trusty camera.

Overall, it looks like a good time was had by all.

Congrats to Pharrell Williams Helen Lasichanh! We wish them years of martial bliss.
