During Adele's current world tour, now on its Australian leg, fans have reportedly been baffled as to how the star makes it on to stage without being spotted.
In many of the venues she's been playing on a stages in the centre of huge arenas, which have no tunnel underneath.
She recently told one audience: "How I get to this stage makes me so sweaty, I'm drenched. I can't tell you til the end — you'll laugh when you find out."
Now the Sun believes has got to the bottom of Adele's mysterious entrance. A source told the paper that the singer climbs onto a large, wheeled flight-case - the type usually used for transporting stage equipment - in which she sits as staff wheel her unseen through the venue to the side of the stage.
The source said “Adele sits in the box for several minutes as she is taken from her dressing room right to the centre of the crowd.
“Most of her fans are already seated and just presume it’s a piece of kit they are moving but some have been told by staff at venues that actually it’s their idol and a woman worth £85million sitting in a pretty small box a few feet from them."
Security guards keep a close watch over the box makes its way past Adele's fans - and the star brings an iPad along for the journey to entertain herself.
“It is a very sweaty and unglamorous part of the show for Adele to get through," the source said, "but she’s down to earth and jokes about it.”
