LOS ANGELES — After months of speculation, Khloe Kardashian is ending her four-year marriage to Lamar Odom.

The Reality TV star filed for divorce Friday in Los Angeles County Superior Court, citing irreconcilable differences. She also wants her last name restored to Kardashian from Kardashian Odom.

The filing comes days after Odom pleaded no contest on Monday to a misdemeanor drunken driving charge.

The 34-year-old athlete was arrested last August after his Mercedes-Benz SUV was seen weaving on an LA freeway.

The 6-foot-10-inch power forward has been out of the NBA since going unsigned as a free agent after a miserable season last year.

Odom had his best years with the Los Angeles Lakers between 2004 and 2011. The team won NBA championships in 2010 and 2011.

Kardashian, 29, is best known for starring with her sisters Kim and Kourtney, and her mother, Kris Jenner, in the long-running reality TV series “Keeping Up With the Kardashians.”

She also runs an upscale clothing store with her sisters and was featured in the short-lived reality series with Odom, called “Khloe & Lamar.”

The two were married in 2009 in a large ceremony that was taped for the E! network.
