Adele's fear of falling ill is keeping her isolated on tour

Los Angeles - Adele is being kept in solitary confinement.

The Hello hitmaker - who is currently enjoying an eight-day residency at London's iconic O2 Arena as part of her 107-date world tour - is keeping herself away from others and has ditched the booze to ensure she's in the best health.

She said: 'I've basically been in isolation because I don't want to get ill. I didn't want to take a chance with my voice. I've been taking echinacea four times a day. I've been on the Beroccas. I'm on a really strict regime. Basically, I'm living on leaves but I do get to eat pasta before the show because it gives me energy for when I get on stage.

"I've got acne. I know we all get spots but you lot ain't got your face on a big screen like that! Imagine trying to pop a spot with these nails - you'll do more damage."

But the 27-year-old singer - who has three-year-old son Angelo with partner Simon Konecki - admits she did enjoy a tipple the other day and ended up "paying for it" later when she suffered from acid reflux.

She told the Daily Mirror newspaper: "I had three glasses of white wine. I did pay for it. It's been a while and wine does give me acid reflux."
