Khloe hired private investigator

Khloe Kardashian reportedly used a private investigator to spy on husband Lamar Odom.

According to Radar Online, a clause in their prenuptial agreement means that the reality star needs concrete proof of her husband’s infidelity, leading to Kardashian’s decision to hire someone to track the basketball star’s movements.  

A source told the gossip site that the investigator discovered that Odom – who is allegedly a regular user of crack cocaine – has had affairs with at least five women.

The insider revealed: "Khloe has not only photographic proof that Lamar cheated on her with at least five different women, but has copies of text messages between Lamar and the other women.

"She is a very smart woman and knew she had to get the proof because of the infidelity clause in their prenup."

Kardashian and Odom – who tied the knot in 2009 after meeting just a month before – are reportedly living separately after she kicked him out of their marital home.

One of Odom’s mistresses, lawyer Polina Polinksy, claims that he lived with her for six weeks in June and July. She also claimed to have seen him using crack cocaine and becoming "paranoid".

A source told Hollywood Life that Odom and Kardashian have not spoken since his arrest for allegedly driving under the influence on 30 August.

"He has been ignoring her calls and texts," the insider claimed. "He just can’t deal with all the pressure right now."

Kardashian has so far refused to address the rumours, but did post a message on Twitter that read: "Sometimes you just gotta be your own hero and save your own little heart.

"Because sometimes, the people you can’t imagine living without, can actually live without you."
