Russian Oligarch Abramovich, Wife Separate

Daria Zhukova founded the popular Garage Museum of Contemporary Art in Moscow and worked with Abramovich on a cultural center in St. Petersburg, New Holland.

Russian billionaire Roman Abramovich and his wife of 10 years, Daria Zhukova, say they have separated.

"After 10 years together, the two of us have made the difficult decision to separate, but we remain close friends, parents, and partners in the projects we developed together," the couple said in a joint statement.

The marriage to Zhukova was the third for Abramovich, who owns the English soccer club Chelsea.

He is ranked No. 139 on Forbes Billionaires List, with a reported worth of $9.1 billion.

Abramovich, 50, and Zhukova, 36, have a 7-year-old son, Aaron, and a 4-year-old daughter, Lea.

"We are committed to jointly raising our two children," they said in the statement.

A prominent figure in the world of contemporary art, Zhukova founded the popular Garage Museum of Contemporary Art in Moscow and worked with Abramovich on a cultural center in St. Petersburg, New Holland.

The couple said they would "also continue to work together as co-founders" of Garage and New Holland.

Abramovich was married to Olga Lysova from 1987 to 1991. He divorced his second wife, Irina Malandina, in 2007 after a 16-year marriage that produced five children.
