Adele, 29, has spent the last 15 months traversing the globe thrilling fans in sold-out concerts in New Zealand, North America, and Europe.
When she performs her fourth and final London date this Sunday, Adele will have completed 125 shows since she started her whirlwind tour of her latest album, 25, last year.
But fans who are attending her London concerts at Wembley Stadium may just do the final sing-a-long with the multiple Grammy-award winner, whose deft and immaculate songs had bowled ballads fans over worldwide, as she left handwritten notes in all of her tour programmes indicating that she may never tour again.
Adele wrote that touring doesn't suit her "particularly well" and just in case she does decide to quit life on the road in future, she wanted to end her shows in her home city.
