British soul singer Sam Smith has won four Grammy Awards in the US, including the prestigious prizes for record and song of the year and best new artist.

Smith was rewarded for being the only solo artist to sell more than a million albums in both the UK and US in 2014.

Pharrell Williams, Beyonce and Rosanne Cash, daughter of country legend Johnny, won three awards each.

Beck won two, including best album. Other British winners included Clean Bandit with Jess Glynne and Aphex Twin.

Madonna, Katy Perry, Rihanna, Kanye West and Sir Paul McCartney were among those performing at the Los Angeles ceremony.

But the night belonged to Sam Smith, who has cemented his place as one of pop's biggest stars just nine months after the release of his debut album In the Lonely Hour.

Accepting the trophy for record of the year, he said: "I want to thank the man who this record is about, who I fell in love with last year.

"Thank you so much for breaking my heart because you got me four Grammys."

Smith also performed his hit Stay With Me on stage with Mary J Blige.

Earlier, he said: "Before I made this record, I was doing everything to try to get my music heard... I tried to lose weight and I was making awful music. It was when I started to be myself that the music flowed."

As well as record and song of the year for Stay With Me and best new artist, Smith won best pop vocal album.

He lost out on the best album award to long-serving indie troubadour Beck, who was honoured for his 12th studio LP Morning Phase. It also won best rock album.

"We made this record at my house for the most part, so I would like to thank my kids for letting me keep them awake a little bit longer," he said.
