The Weeknd

Adele and The Weeknd had the biggest global hits of 2021

Adele's highly-anticipated fourth album sold more than five million copies in just two months, said the IFPI.

It was the biggest-selling record on vinyl and CD, the industry body added.

Meanwhile, The Weeknd's moody retro-pop ballad topped the charts in 18 countries, and was streamed 2.15 billion times.

It was the second year running that the Canadian star delivered the world's most popular song.

Last year's chart-topper, Blinding Lights, made the top 10 for a second time in 2021, at number seven.

Selena Gomez and The Weeknd reportedly split

A source told People magazine that things "have been hard for months" for the Gomez, 25, and The Weeknd, real name Abel Tesfaye, 27.

"She and Abel have been going back and forth for a few months about their relationship... It's been hard with him being on tour and her shooting in New York. That wasn't easy on them."

The couple first started dating in January, before making their first official debut outing as a couple at the Met Gala in May.
