Rihanna at the first Diamond BallThe inaugural Diamond Ball was held last night on the sprawling grounds of The Vineyard in Beverly Hills. The annual event was created to raise funds for the Clara Lionel Foundation. The foundation is a charitable organisation established in honour of the singer’s grandparents and it raises funds for cancer treatment as well as education, arts and culture. This is a cause that is very dear to Rihanna’s heart. The Diamond Ball was attended by the top echelon of Hollywood and guests included Brad Pitt and Salma Hayek. Comedian Jimmy Kimmel played the role of host throughout the night and there was an auction and a special performance by Rihanna herself. Here’s a look at what the lady of the moment wore.
