Jet-set beauty Goga Ashkenazi, a friend of Britain’s Prince Andrew, and a lover of billionaire Timur Kulibayev, hosted her $1 million annual bash in St. Tropez last night at the historic Chateau de St. Amé. Last year, the Kazakhstani-born businesswoman had Grace Jones perform, and one female guest infamously jumped onstage, took off her top and danced with Grace before security removed her. This year Ashkenazi — who recently bought iconic French label Vionnet — asked R&B star R. Kelly to perform. Goga was expecting close to 500 people for the 9 p.m. dinner — with an “out of this world” dress code (whatever that means) — and concert. The beauty rented the chateau for $165,467 and was expected to spend more than a million dollars on the extravaganza. With Denise Rich’s annual party canceled, Goga’s bash could end up being the highlight of the Riviera party scene. Also spotted in St. Tropez were Kate Moss, Reggie Bush, Ivana Trump and Liam Neeson, who was holding hands with a mystery beauty over lunch at Bora Bora.
