Lewis Capaldi was the big winner at the Brit Awards at London's O2 Arena on Tuesday night, winning Song of the Year and New Artist of the Year.
Capaldi joked onstage that some people thought his Song of the Year, Someone You Loved was about his ex-girlfriend, Love Island contestant Paige Turley.
He said: "A lot of people think it is about my ex-girlfriend, who you can now see every night on Love Island.
"It was actually about my grandmother, who sadly passed away a few years ago."
He added: "Thank you so much, this has been the best year of my life."
The ceremony also saw Billie Eilish winning International Female Solo Artist; Mabel named Female Solo Artist and Stormzy honoured with Male Solo Artist. Capaldi, Eilish, Mabel and Album of the Year winner Dave are all first-time Brit Award-winners.
Tyler, The Creator won the International Male Solo Artist gong. Irish singer-songwriter Dermot Kennedy had been nominated in the category.
After collecting his first-ever Brit Award, Tyler, The Creator jokingly thanked former British Prime Minister Theresa May, who he said had previously stopped him entering the country.
Foals were named Best Group - another first win. Celeste accepted her previously-announced Rising Star award.
Mabel opened the show with a big production performance of her hit Don't Call Me Up.
As she collected her Female Solo Artist award she saluted her mother, singer Neneh Cherry.
Host Jack Whitehall paid tribute to the late broadcaster Caroline Flack at the start of the show.
He described Flack as a "kind and vibrant person with an infectious sense of fun", adding: "She will be sorely missed. I'm sure I speak for everyone when I say that our thoughts are with her friends and family."
Whitehall then introduced Lewis Capaldi performing the Song of the Year, Someone You Loved.
Harry Styles, who dated Flack at the start of his One Direction career, gave a very moving performance of his ballad Falling. He had earlier been photographed on the red carpet wearing a black ribbon on his lapel.
The show also saw Billie Eilish giving the first performance of the new Bond theme, No Time to Die; Lizzo singing a medley of her hits and Album of the Year winner Dave turning up the political heat with his track Black.
Stormzy may have won the award for performance of the night:
