Khloe Kardashian is ready to finalise her divorce from Lamar Odom.

The 30-year-old reality TV star, who filed court documents seeking to end her four year marriage to the former LA Lakers player in December 2013 amid rumours he cheated on her and was addicted to cocaine, is said to have ''finally reached a breaking point'' because he is allegedly back on drugs.

A source close to the 'Keeping Up with the Kardashians' star said: ''Lamar has fallen off the rails again. They were trying to work things out, but Lamar isn't shaping up well at all. He recently left his home and he's now staying with a cousin of his. He can't handle his bills, his career, or his life.

''Khloe's now kicking herself for falling for his bulls**t lies. She knows she is totally in love with [him], but she's now realising it is time to move on and divorce him.''

The duo were recently rumoured to be holding secret talks in a bid to reconcile and even discussed filming another series of 'Khloe & Lamar' to prove to their fans they were meant to be.

But the insider added to Life & Style magazine: ''The Khloe and Lamar show is on hold indefinitely.''

The 35-year-old athlete recently insisted Khloé is ''still my girl.''

Asked if there is a chance they'll get back together, he said: ''Of course. That's still my girl. Of course. That's my wife.''
