Russian billionaire and Chelsea Football Club owner Roman Abramovich and his wife of 10 years, Dasha Zhukova, have announced their separation.

Abramovich is estimated to be worth $11.5 billion and is famous for his high-profile assets including Chelsea Football Club and a string of luxury properties, cars and yachts.

He’s reportedly dropped more than $1.5 billion on “toys and homes” including ones in the Caribbean, Colorado and the South of France.

He’s also renowned for hosting lavish parties where the likes of Beyonce and Gwen Stefani would perform or dropping $50,000 on restaurant bills in New York City.

Zhukova, 36, is no stranger to the high life herself. The daughter of a Russian oligarch Alexander Zhukov, who has made a small fortune in oil, metals and banking, she has been lauded by the New York fashion and arts scene for her daring projects.
