The 33-year-old, known for her ballads about break-ups and regrets, teased her new single “Easy On Me” last week with a short video clip.

The song is the first to be released from her upcoming fourth album “30”, out next month.

On Wednesday, Adele told fans she was “finally” ready to release “30”, which she described as her “ride or die throughout the most turbulent period of my life”.

“I was certainly nowhere near where I’d hoped to be when I first started it nearly three years ago,” she said on Twitter. “Quite the opposite, actually. I rely on routine and consistency to feel safe, I always have.

“And yet there I was knowingly – willingly even – throwing myself into a maze of absolute mess and inner turmoil.”

In interviews with fashion magazine “Vogue”, Adele, who has named her albums after milestone ages in her life, said she had written “30” to explain her divorce to her young son, Angelo. Adele split from charity executive Simon Konecki in 2019.

“I’ve learnt a lot of blistering home truths about myself along the way. I’ve shed many layers but also wrapped myself in new ones,” she said on Twitter.

Known for hits like “Someone Like You” and “Hello”, Adele is one of the most successful singer-songwriters of all time, storming charts around the world and winning 15 Grammys as well as an Oscar for James Bond movie theme song “Skyfall”.

Earlier this month, fans had speculated new music from Adele was imminent after mysterious “30” signs appeared on buildings around the world.

“When she releases music, not only does it generate a lot of sales around her work, but it acts as a halo towards British music. It gets people into stores, buying online, and streaming as well,” said Gennaro Castaldo from record labels association BPI.

“She’s one of the few global superstars that can actually achieve that sort of impact.”
