Khloe Kardashian hired private investigator to follow Lamar Odom for a year

Khloe Kardashian has reportedly had a private investigator following her husband Lamar Odom for the past year.

The private investigator uncovered evidence that the NBA player had cheated on his wife with up to five mistresses, according to RadarOnline.com.

Only two of those women — Polina Polonsky and Jennifer Richardson – have been named publicly to date.

Khloe seemingly had her husband followed because of an infidelity clause in the couple’s prenuptial agreement, a source told RadarOnline.com.

“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,” revealed the insider.

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

As a result, drug-troubled Odom could be forced to pay Khloe a “very large lump sum of cash, or a very hefty spousal support” if the couple does end up divorcing, said the source.

There’s a lot at stake in this high-priced marital crisis, too.

Both sides of the Hollywood power couple have bank accounts: Khloe is worth approximately $18 million, while Odom has socked away some $56 million during his 14-year career.

The couple also have homes, cars and businesses together which would all have to be dived up should the pair divorce.

Lamar has been living at his apartment in Downtown Los Angeles for the past few weeks after reportedly rejecting three separate interventions from those close to himwho want him to seek help for his addictions.
