'He Will Continue To Cheat On You': Lamar Odom's FIRST Mistress Jennifer Richardson Warns Khloe Kardashian

Jennifer Richardson, the 29-year-old woman who Lamar Odom carried on a year-long affair with behind Khloe Kardashian's back, has a sad-but-simple message for the youngest of the three Kardashian sisters: If he did it before, he will do it again.

"He will continue to cheat on you," she said in an open letter to InTouch, admonishing Khloe to move forward with what's in her heart.

"Take all that you know and make the decision for Khloe Kardashian Odom, not Khloe Kardashian the brand," wrote Richardson, a stunning brunette who met Lamar in Washington, D.C. while he was on the road with the Los Angeles Clippers.

In the letter, she also nudged the 29-year-old reality TV star to break her silence in regards to her husband's infidelities.

"Your fans and so many young women look to you for strength," she said, "they deserve to know your marriage is not perfect."

Richardson makes clear in the letter that her "intentions are not, and never have been, malicious or to harm your marriage.

"Never did I ever think I'd take on the role of 'The other woman," she wrote, imploring Khloe to move forward in her union with caution.

"Trust is the hardest thing to gain and easiest thing to lose in a relationship."

The letter comes on the heels of our exclusive story unmasking attorney Polina Polonsky as the second woman Lamar carried on an affair with during his four-year marriage to Khloe.
