Khloe Kardashian finds out about Lamar's 5 mistresses

Khole Kardashian's private investigators have revealed that her husband Lamar Odom had 5 mistresses.

The 29-year-old reality star had her basketball player husband followed by a private eye to investigate the cheating rumours, due to an infidelity clause in the pair's pre-nup agreement, Radar Online reported.

The investigator uncovered evidence which stated that Odom indeed cheated on her with 5 different women.

Only names of two women, Polina Polonsky and Jennifer Richardson, had surfaced earlier, regarding their relationship with Odom.

A source has revealed that the 'Keeping Up With The Kardashian' star not only has photographic proof that her husband cheated on her, but also possesses copies of text messages between him and the 5 women.

The insider said that Kardashian is a very smart woman and knew that she had to get the proof.

The source added that Odom now might be forced to pay Kardashian a "very large lump sum of cash, or a very hefty spousal support" if the couple does end up getting a divorce.
