The clock is ticking on Khloé Kardashian Odom and Lamar Odom's marriage. Rumor has it that a new deadline has been set: Khloé wants to be divorced before her sister, Kim Kardashian, and Kanye West wed.

According to HollywoodLife.com, Khloe wants her marriage from Lamar to be over before Kim and Kanye's wedding because she does not want to still be a part of a failing marriage while Kim is starting a successful one.

"Khloe doesn't want to be a wreck at the wedding, watching her sister and Kanye embark on their lifelong journey of love together while she's still in a fucked up marriage that's going nowhere," "a source connected to Khloe and Lamar" told HollywoodLife.com.

Khloé, 29, allegedly already told Lamar, 34, that he is not invited to Kim and Kanye's wedding. Apparently, Kim has replaced Lamar as Khloé's priority.

"She loves her sister so much and doesn't want to have any negative energy or be in a bad place when she and Kanye marry each other," the HollywoodLife.com source said.

Lamar, however, is already prepared. According to the tabloid website, Lamar is expecting to see divorce papers before the holiday season ends.

"He knows it's not going to last," a HollywoodLife.com "source close to Lamar" said. "He already knows, and there's nothing he can do about it. He's expecting Khloe to end things."

Khloé, on the other hand, might be waiting for some things to pan out before she leaves her husband. Another Hollywoodlife.com source that is "close to" Khloé claims that the reality star is still looking out for her business prospects.

"The divorce plans are very calculated," the source said. "Not only does Khloe want to wait until after the holidays, she also wants to wait to see if Lamar will sign with an NBA team [because] she would want him to finish the season drama free. Plus, she wants to work around the television show storylines. As crazy as this all sounds, Khloe is business first, divorce afterwards."
