Grammys 2015: Sam Smith and Pharrell Williams Win Big in Pop Categories

Pharrell Williams and Lang Lang

With a bilingual spoken section, a "Hands Up, Don't Shoot" gesture and a very minor introduction with heavy strings, Williams refreshed his Despicable Me 2 hit "Happy" with a piano interlude with Lang Lang — and Hans Zimmer on guitar. He was dressed in a bellhop-like outfit, noting at the end of his performance, "As you can see, I'm at your service, Lord."

Sam Smith and Pharrell Williams were among the pop artists to take home trophies at Sunday's Grammy Awards, held at Staples Center in Los Angeles.

Sam Smith and Pharrell Williams won big in the pop categories at the 57th annual Grammy Awards on Sunday evening.

Williams took home the award for best pop solo performance for "Happy (Live)," beating out John Legend's "All of Me (Live)," Sia's "Chandelier," Sam Smith's "Stay With Me (Darkchild Version)," and Taylor Swift's "Shake It Off."

"I'm not going to make this awkward and long because I was so prepared for everybody else that is so talented in that category to walk away with that award. I'm honored, actually, to be grouped with them," he said while accepting the award. But after he had thanked his team and Columbia Records, he admitted with a laugh, "This is super-awkward, and I'm going to moonwalk my way off the stage right now."

Best new artist winner Sam Smith won his second Grammy of the night over five other nominees including Coldplay, Miley Cyrus, Ariana Grande, Katy Perry and Ed Sheeran for best pop vocal album for In the Lonely Hour.

For best traditional pop vocal album, Tony Bennett and Lady Gaga took the trophy for Cheek to Cheek, which was up against Annie Lennox's Nostalgia, Barry Manilow's Night Songs, Johnny Mathis' Sending You a Little Christmas and Barbra Streisand's Partners.

In pop's only collaborative category, A Great Big World and Christina Aguilera's "Say Something" won best pop duo/group performance. Other nominees in the category included Iggy Azalea and Charli XCX's "Fancy," Coldplay's "A Sky Full of Stars," Jessie J, Ariana Grande and Nicki Minaj's "Bang Bang," and Katy Perry and Juicy J's "Dark Horse."
