Pharrell Williams caused quite a stir at the 57th Annual Grammy Awards on Sunday. First, he and model wife Helen Lasichanh arrived on the red carpet sporting casual outfits for the formal affair. Williams posed in a white jacket, shirt, bow tie and shorts, which is part of his collection for Adidas, while Lasichanh wore a grey Adidas jumpsuit with black heels.

"I usually wear shorts. That's just like my thing," Williams told Ryan Seacrest on the red carpet.

The R&B singer and producer dazzled the stage at the 2015 Grammys with a surprisingly different performance of his 2014 smash-hit, "Happy," reports Hollywood Life. Dressed like a bellboy, Williams, 41, began the feel-good song by replacing its usual upbeat temp with a haunting minor-key orchestral accompaniment written by film composer Hans Zimmer who joined him on stage. Zimmer added an electric guitar to the number, which also featured Chinese classical pianist Lang Lang, a string orchestra wearing yellow robes, a gospel choir and multi-ethnic dancers and singers.

The performance, one of the most powerful musical numbers of the ceremony, added a dash of controversy when it eluded to a racial clash last year by outfitting dancers in dark hoodies who lifted their hands, mirroring the "Hands Up Don't Shoot" protest reminiscent of Michael Brown's fatal shooting in Ferguson, Missouri, and to pay tribute to the #BlackLivesMatter movement. Midway into the performance, the song reclaimed its lively tempo, shifting into its signature mood of celebration.

Williams' gesture was noticed by Ebony.

"What a statement on music's biggest stage. @Pharrell shows #BlackLivesMatter with his 'Hands Up, Don't Shoot' tribute. #GRAMMYs," the magazine tweeted

His "Happy" performance wasn't the only Grammys moment for which Williams made headlines. When pop singer Taylor Swift was dancing in the audience to performers, Williams was caught on camera seemingly giving her major shade.

The now eight-time Grammy winner took home three Grammy awards: Best Pop Solo Performance and Best Music Video for "Happy" and Best Urban Contemporary Album for his album "Girl." Williams tied Sam Smith and Beyonce for most Grammy nominations this year with six each.
