Korean entertainer and race car driver Ryu Si-won is reported to be in divorce proceedings.

Local dailies reported Monday that Ryu’s wife had filed for divorce on March 22, seeking to end the couple’s 18-month marriage.

The reasons for the split have not been disclosed.

On Monday, Ryu canceled the annual pre-race event for his team, EXR Team 106, scheduled for April 17. R’s Company, Ryu’s entertainment firm, explained that the cancellation was due to personal matters.

R’s Company said through a press release that Ryu has not yet reached any decisions and that the couple may avoid a divorce if they can talk through the matter in a mature manner.

Ryu ended the three-year hiatus in his acting career with Channel A’s new weekday TV drama, “Goodbye My Wife,” scheduled to air starting May 7.

Ryu married in October 2010 and the couple’s daughter was born in January 2011.
