Adele is forced to keep herself in ''isolation'' as she continues her world tour because she doesn't want to get ill. 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.''..
