Rumors surfaced that Kardashian has split from her rapper boyfriend for the second time because she is not ready to have a serious relationship, New York Daily News reported.
The reality star allegedly ended the love affair due to commitment issues.
"Khloe just wasn't ready after Lamar and it was getting too serious. She respects and cares for him but just wasn't ready," the source said, according to US Weekly.
Last September, the couple ended their 8-month relationship. "Our relationship - you break up you make up, you break up you make up. We went through that a couple times. You never know," Montana said.
The following month, the rapper declared his love for Kardashian in an interview. "She's my baby forever. She's good. She's the best. There's no bad blood with her. I love how she is. She inspires me as a person. I'm sure I inspire her in many different ways," Montana revealed.
The couple got back together after Montana hinted on several interviews. The rapper confirmed that they are still in a special zone.
Last November, Kardashian greeted Montana on his birthday and posted a photo on Instagram with the caption:
"Happy birthday baby boy! In only a short amount of time we have created timeless memories. Happy birthday to a man who genuinely lives life to its fullest. "What's understood doesn't need to be explained" @frenchmontana I can't wait to celebrate life with you tonight! You deserve it!"
However, on Tuesday, the reality star posted a cryptic message on the social networking site that reads:
"The saddest word in the whole wide world is almost. He was almost in love. She was almost good for him. He almost stopped her. She almost waited. He almost lived. They almost made it."
Meanwhile, the pair has not released an official statement to address the second break up rumors.
