Adele's crew get medical checks every week
Adele gets a doctor to approve which members of her crew she can speak to so she doesn't get ill.
The 'Hello' singer was forced to cancel a gig in Phoenix, Arizona, last month, after falling sick with a cold, and is so concerned about the thought of contracting anything else, she has a medic assess her team once a week and either give them a badge of approval or place them in "quarantine".
According to The Sun newspaper, she told her audience in Michigan on Wednesday (07.09.16): "I had to cancel a show on the last leg of my tour in Phoenix, Arizona and I've actually never been so devastated in my life.
"We have a doctor that comes in once a week that comes in and everyone gets a badge so I know I can go up to them and talk to them.
"So everyone gets a badge and if they've got a badge it means I know I can go up to them and be like, 'Hi, how are you?' and touch them. If they don't have a badge, you are quarantined."
But Adele isn't entirely healthy as the 28-year-old singer - who has a three-year-old son, Angelo, with partner Simon Konecki - admitted she has got sunburnt after spending her two-week break at her Los Angeles home.
She said: "I've actually just had a two week break. So I was living it up in LA having a nice holiday, sunbathing without any sun cream so I'm very, very burnt under all of this."
The 'Skyfall' hitmaker was devastated when she had to cancel the show last month.
She said in an Instagram video: I'm really, really sorry. I've had a cold for a couple days, and I've been pushing through it and I did my show last night and I loved it, but I pushed too hard. And my cold has gotten the better of me.
"As you can hear, even if I did the show, it wouldn't be very good.
"I'm really, really, really sorry to let anyone down.
"I've enjoyed my tour so much and cancelling shows is not something I want to do. I've pushed through a lot of things that I've been trying to sing all morning and warming up and nothing is really happening."
