London, Oct 31 (IANS) Singer Robbie Williams, who is now sober and drug-free, says he was once tripping on magic mushrooms U2 frontman Bono's house.
The 42-year-old singer opened up about his hedonistic past in an interview with The Irish Times, reports mirror.co.uk.
Williams took the drugs on a night out, before heading to the Bono's luxury property, an experience which left him a little confused.
Williams said: "I remember a great psychedelic time - by psychedelic I mean mushrooms. I arrived at Bono's house, let's say I was already elsewhere. I was looking at the best painting in the world I had ever seen. My mouth dropped to the floor, thinking 'Wow, Bono has the best painting I have ever seen'...Then Bono appeared. I told him, 'Hey, you got the best painting I have ever seen, and Bono said: 'Robbie, you're looking at the window'."
Williams has been open about his battle with drink and drugs - issues which started in his teens.
