NBA Star/Khloe Kardashian's Husband 'Lamar Odom' Missing For Three Days

Friends and family of the NBA forward have been unable to contact him for 72 hours, the TMZ website first reported.

The 33-year-old, who played last season with the Los Angeles Clippers, is reported to have gone missing after refusing to go into drug rehabilitation.

Last year, he went to a rehab centre in San Diego at the request of his wife, but left after three weeks.

Khloe wrote on her Twitter page:

A source close to Lamar Odom told ESPN that friends were reportedly trying to get him some help for an "unspecified drug problem" after he was found in an L.A. hotel room. Sports Center tweeted:

The couple have been at the centre of rumours surrounding their marriage.

They married in September 2009 and their wedding was featured on the reality show Keeping Up With The Kardashians. The couple also had a spin off series.
