It seems like Khloé Kardashian and estranged husband Lamar Odom are rekindling their relationship, as they have reportedly been seeing each other secretly for the past couple of weeks.

According to Life & Style, the "Keeping Up with the Kardashians" star and the former NBA basketball player wanted to meet up over the weekend to celebrate their fifth wedding anniversary.

"She's been calling him again -- and they made plans to secretly see each other around their anniversary, Sept. 27," a source revealed. "Lamar has made it clear to Khloé that he is still in love with her and will do anything to be with her again. And Khloé's been missing him -- especially now that she and French are done."

"She is so over French," the source continued. "Khloé misses being Lamar's wife. A part of her wonders if maybe they can rekindle and pick up where they left off!"

Following her recent split from rapper boyfriend French Montana, Kardashian has been talking to Odom almost every day. "Things between her and French had been fizzling out for a while and she was speaking to Lamar almost daily," another source told Heat. "They've been meeting in secret for the past couple of weeks. Lamar never wanted to let Khloé go and has been desperately trying to get her back."

Moreover, the couple has been hanging out together in the same hotel room where they started dating. "She's meeting Lamar at a suite in the SLS in Beverly Hills -- where Lamar was living when they first met," the sourced continued. "It's where Khloé says they fell in love. They've even been eating pancakes in bed just like they did back in the day."

In addition, Lamar Odom has been receiving treatment for alcohol and drug addiction, in an effort to prove Khloé Kardashian that he is a changed man.

"Khloé's back in lust, but she knows it's dangerous and she isn't sure whether he really is the changed man he says he is," the source added. "Lamar's promised Khloé he's on a strict weekly rehab maintenance program. He's also been working on his mental health issues with therapy and has vowed to do whatever it takes to get her back."
