Khloe Kardashian has reportedly told Lamar Odom she wants a divorce, with Khloe allegedly informing him on their fourth wedding anniversary last Friday that she is preparing to file papers to formally end their marriage following kicking him out of their house in in August after a failed intervention to get him to go to rehab.

According to Us Weekly: 'She called him on their anniversary and told him she'd be filing for divorce. She wanted to give him fair warning. Khloe was very firm. She said she will be filing soon and she thinks it's best they move on. Khloe told Lamar she hopes he gets the help he needs.'

Khloe also recently changed her name on her Instagram and Twitter profiles by removing her last name Odom. The insider said: 'Changing her name on social media was a big step in letting people know she is moving on.'

Meanwhile Lamar doesn't think he needs rehab to beat his drug problems, according to TMZ.

Following his very short spell at a treatment centre early last month to get help for his alleged crack cocaine problem, Lamar is said to have been clean for five days now and thinks he can maintain his sobriety without attending a clinic.

TMZ's sources close to him say that Lamar believes in 'self-healing' and is hoping to overcome his problems through his own willpower as he has done it successfully before, and is willing to consider professional help but refuses to do so through rehab centres, preferring private measures. Another step he's apparently making is cutting out certain 'friends' who he thinks may be a bad influence to make sure he does not relapse.

This news comes after both the Los Angeles Clippers and Los Angeles Lakers decided against giving him a contract to play for the upcoming season in the wake of the revelations about his personal life.
