Khloe Kardashian's husband Lamar Odom was arrested for driving under the influence in the early hours of Friday morning.

The NBA star, 33, is being held in Van Nuys jail on $15,000 bail, LAPD confirm. 

He was pulled over just before 4am for driving too slow (50mph) on the 101 Freeway in the San Fernando Valley.

He and did not immediately respond to police, passing three exits and driving in a 'serpentine manner' before stopping, according to TMZ.

He failed numerous field sobriety checks but refused all chemical tests, the website claims. 

It follows weeks of troubling allegations about drug abuse and serious marriage issues with his wife of four years. 

Reports claim he has been battling an addiction to 'Oxycontin and crack cocaine' for two years.

He has also been accused of cheating with two different women while on the road as a basketball player.

Loyal wife Khloe, who was pictured looking downcast as she arrived at a LA gym on Thursday, is apparently desperate to 'save' her husband from his alleged drug problems and work through their marital woes. 

A source has said: 'She is in love and does not want a divorce.'

Both have been pictured with their wedding rings on separate outings this week. 

The Keeping Up with the Kardashians star reportedly staged an intervention earlier this month, but the meeting didn't go as planned and Lamar vanished, but was later tracked down to a hotel in Los Angeles. 

He returned to his L.A. home on Monday after staying away for several days.

Khloe apparently kept the details of her marital problems a secret from most members of family, and insiders say they were 'shocked' to learn of the extent of the issues.

Lamar won on two NBA championships as a member of the Los Angeles Lakers but his career is now in tatters. 

'Players are starting to return to their teams, and Lamar doesn't have a team,' an NBA insider told People. 'He's gone from making $8.5 million last year to being out of work at this point.'

He became a free agent on July 1 after his contract with the LA Clippers ended.

Burton additionally confirmed that Antwan Jamison is expected to be officially signed to the Clippers on Wednesday, which would leave no room for Lamar on the team's roster.

'There's an old saying in the NBA: Are you more valuable than your problems? And it's just reached the point with Lamar where he is not more valuable than his problems,' the insider said.

'Up until about two years ago, Lamar Odom was averaging about 15 points and eight rebounds a game and you know what? You deal with his off-court problems for that. When Lamar Odom averages four points a game, he's not worth the problems.'

However the source added that Lamar could still be in with a spot on the Los Angeles Lakers, although he would probably have to take a significant pay cut.
