Khloe, 30, 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, reported Contactmusic.
"Lamar has fallen off the rails again. They were trying to work things out, but Lamar isn't shaping up well at all. He can't handle his bills, his career, or his life," a source said.
"She knows she is totally in love with (him), but she's now realizing it is time to move on and divorce him," the source added.
