Khloe Kardashian and Lamar Odom might be giving their marriage a second chance but apparently there's one person who is none too happy about their reunion. Khloe's sister Kim Kardashian is furious over the fact that the two are rekindling their love, as she thinks it's a bad idea that might eventually see her Khloe get very hurt in the end.

Even before Lamar was found unconscious in a Nevada brothel after a three-day drug binge almost two weeks ago, Kim has had her concerns about the former NBA star, advising her sister to get a restraining order against him.

"She just doesn't think he's right for Khloé," a source reveals to Hollywood Life. "Kim thinks he's unpredictable and would hate for Khloé to give him her heart again and he stomp on it just like he did the first time."

Khloe has been by Lamar's bedside ever since he was rushed to a Las Vegas hospital and has vowed to support him as he regains his health. Kim meanwhile thinks that she might be doing too much too fast and that she'll be the one left more broken than Lamar in the end.

The insider added, ""Kim was not expecting Khloé to make such a huge decision like this under the current circumstances. She's still apprehensive about Lamar."

Khloe and Lamar separated back in 2013, but their divorce was never finalized, due to a backlog of paperwork in the Los Angeles court system.
