Khloe Kardashian's divorce is reportedly being stalled because Lamar Odom isn't ready to let go yet. According to a new report, the NBA player wants to win back Kardashian, who filed for divorce in December.

It's been six months since Kardashian and Odom split but they are still legally married because the athlete reportedly refuses to sign the divorce papers, Life & Style magazine reports (via Hollywood Life).

"Lamar wants Khloe back," a source told the magazine. "He does not want to end the marriage, and that's why he won't sign the divorce papers. He just won't let her go. He's sober and back on track now - and thinks he can get her back."

It seems like the reality star has already moved on from the failed marriage with rapper French Montana. It's been rumored that Montana and Kardashian have been dating for at least a month, and neither one is trying to hide the romance.

The two have been spotted out-and-about on several different occasions and reportedly even bought his and hers watches in New York City. The owner of Rafaello & Co. in Manhattan told Hollywood Life that Kardashian and her new man came in and purchased some very expensive diamond watches.

"I dealt with Khloe years ago and I've dealt with French many times and they called and said they wanted to see some stuff," owner Gabriel Jacobs said. "They are matching Rafaellos - new ones, rose gold. French's is about 15 carats and hers is about 7 carats."

"They just came by like regular clients, no filming," he added. "They seem like a regular couple. They seem cool, very happy."

There was also a rumor that Odom was beginning to move on as well. According to a previous report by US Weekly, the athlete had finally started dating again.

"Lamar is busy with training and is concentrating on his own life," the source said. "At first he was pissed about French Montana, but now he doesn't care."

"Lamar had a few dates with non-famous girls, but he's not serious about anyone yet," the source added.
