What do you get when you put a rock star, a movie star and a prince in one room? Oh, just another ordinary birthday celebration for rocker Bono. The singer had an intimate dinner party at Sass Café in Monaco on Friday, and the guest list included Brad Pitt and Prince Albert II. Angelina Jolie, however, stayed at home and didn't make the party. The sit-down dinner started at 10 p.m. and guests toasted the birthday boy with champagne and strawberry cake. Happy Birthday, Bono!
