British singer Ed Sheeran's 'Thinking Out Loud' has won the first major Grammy at the music awards, locking rapper Kendrick Lamar out of a potentially historic win.
Sheeran's win meant Lamar would not make history for the first rap single to win song of the year.
However Lamar, who went into the awards with 11 nominations, won five early in the evening, including best rap album Grammy for his critically acclaimed 'To Pimp A Butterfly'.
In accepting the award, Sheeran said: "My parents have flown to the Grammys for the last four years, and every time I lose, they're like, 'Maybe next year!'"

"You can't read Braille," he said, holding up the paper to the camera.
Sheeran, 24, who had earlier won best pop solo performance for the same track, paid tribute to the Motown legend.
"If you had told my five-year-old (self)... I'd receive an award from Stevie Wonder, I'd be shocked," Sheeran said.
Sheeran's win was big on social media.
