The lead singer of the world famous U2 band, Bono, celebrated his birthday last Friday night at Sass Café in Monaco and it was not an ordinary birthday party at all. The list of the invited guests to the birthday party goes like this: Brad Pitt, the U2’s lead guitarist The Edge and Prince Albert II of Monaco. The café manager said that it was a surprise party as they received a call to organize the same late on that afternoon. The dinner was all arranged by Bono’s wife Ali Hewson and the guests were treated with red wine at the dinner table. A champagne toast for Bono and a candle lit strawberry cake followed right after the meal.
