Lamar Odom reportedly refuses to divorce Khloé Kardashian.

A source told Us Weekly magazine: "Khloé can't even get in touch with him right now."

Another insider said: "He refuses to sign the divorce papers."

A friend close to Lamar, 34, said he is still hoping to repair their marriage, even though Khloé has moved on and recently split from rapper French Montana after eight months of dating.

Lamar has been keeping a low profile since he was dropped by the New York Knicks for failing to "uphold the standards to return as an NBA player" over the summer.

The athlete has been sending Khloé and her mother, Kris Jenner, flowers on a regular basis in a bid to win her back.

A source recently said: "He sends her favourite flowers all the time just to make her smile.

"Kris has always held a special place in her heart for Lamar, so when he reached out to apologise to her too, she was like putty in his hands.

"Lamar knows that even if he earns Khloé's trust back, it's her mom who makes all the family decisions. He's thrilled they're talking again."
