Lamar Odom's marriage to reality star Khloe Kardashian might still be on, however, there is no more romance, as far as Khloe is concerned. A new report has emerged claiming that Kardashian is "furious" with Odom's negative allegations towards her exploiting his health crisis.

 "Khloe's really upset and she feels so used," a family insider reportedly told Radar Online on November 10.

"She did everything with [Lamar Odom's] best interests at heart and thinks he's being ungrateful," adds the insider.

In addition to insisting that Lamar Odom's marriage with her is not romantic, Khloe Kardashian, 31, is currently dating James Harden, 26.

Many are expecting to find Lamar Odom's marriage crisis and his health battles on "Keeping Up with the Kardashians." However, the site has not yet officially confirmed his story will appear.

According to the source, his recent hospitalization will reportedly be included. In addition, the source claims that Odom has been angry at Khloe for allegedly blocking family members from visitation.

Radar Online however claims Khloe wasn't involved in such aspect of Lamar's health care.

"Khloe insists she had no say in who could come and see [Lamar Odom]. She can't believe he's the one accusing her of using him when she feels it's the other way around," said the Radar Online source.

"She's really hurt that he would lash out at her - it's something he's never done in the past," the source added.

Currently, Lamar Odom is reportedly in an "extremely fragile state both physically and mentally," which could be the reason for his negative feelings toward Khloe.

According to The Inquisitr, on Monday while at the signing of her book ,"Strong Looks Better Naked" at The Grove in Los Angeles, Khloe revealed her and Lamar Odom's marriage status in an interview with NBC News. Kardashian reportedly said that she is trying to navigate through his current health crisis.

"I'm still married for a multitude reasons, but intimacy is not one of them," Kardashian said, afterwards insisting that Lamar is aware of her relationship with Harden.

According to Kardashian, Lamar Odom's marriage with her and his crisis has made her reassess what's important in her life. This is reportedly the reason for the postponed press events of her new memoir. Khloe announced the temporary cancelation of her tour via Twitter.

Lamar Odom's marriage with Khloe Kardashian began as a whirlwind romance in 2009. They married in December of the same year after months of dating. They separated in December 2013. This July, while the two exes have already signed divorce documents in Las Vegas, the finalization of their divorce was halted on October 13 after Odom was found unconscious in a brothel in Nevada, according to Us Magazine.

He is currently recovering, after recently overcoming near kidney failure, multiple strokes, and several other serious health conditions.

"Keeping Up with the Kardashians" airs Sunday, November 15, at 9 p.m. on E! There's still no schedule when Lamar's health crisis will be featured.
