Khloe Kardashian may be in an on-again, off-again relationship with French Montana, but the rapper may have reason to worry because KoKo might not be over her ex, Lamar Odom.

Fans have watched Khloe struggle with her separation from the former NBA player on "Keeping Up With the Kardashians" and despite Odom's infidelity, rumored drug use and supposed refusal to sign divorce papers, the reality star admits if she had her way she would still be married.

On an upcoming episode of "Kourtney & Khloe Take the Hamptons," Khloe vents her frustration to her mom, Kris Jenner, who thinks she's moving on too quickly from Lamar to French.

"I know that the relationship that you thought you had didn't work out and it sucks," Kris says to Khloe in a preview of Sunday night's episode. "It makes me cry every time I think about it, but you met somebody new and you moved from one thing to another so quickly -- I'm just trying to be here to support you."

Khloe responds by defending her new relationship with French, who she seems to have recently reunited with in after a brief breakup. The pair even celebrated French's birthday together this month.

"Don't say I moved to something so quickly because you know for how many f--king years I was dealing with something," Khloe says. "Don't you dare say how fast I moved on to something so quickly. You're so simple-minded; you don't know how I feel every day. If I had my way I would still be married to Lamar."

She continued, "Even right now today I wish I was still married to him."

Khloe filed for divorce from Lamar last December, citing irreconcilable differences. The couple were married in 2009.
