Khloe Kardashian And Lamar Odom Marriage UPDATE: After Proving Her Husband’s Infidelity Through Her Hired Private Detective, Reality Actress Had Herself Tested For STD

Following her husband's cheating scandal, Khloe Kardashian recently underwent tests for sexually transmitted diseases.

"Khloe was physically sick to her stomach when Lamar admitted that not only had he cheated on her, but didn't use protection 100 percent of the time. Lamar refused to admit to how many women it was, but Khloe knew it was at least five different women in the past year," the source told Radar Online.

The source also emphasized how disgusted the actress was: "Khloe knew she had to go to the doctor, and was tested for a full range of sexually transmitted diseases. She is healthy, thankfully, but never thought this would happen to her. It's bad enough that Lamar betrayed their marriage vows but to place her health in jeopardy is disgusting."

It was early last year when the 'Keeping Up with the Kardashians' actress sensed something was wrong with her marriage. Apart from her husband's alleged substance addiction, several women including Sandy Schultz, Polina Polonsky, and Jennifer Richardson also came forward claiming sexual relationships with the NBA player.

Kardashian then decided to make a smart move. She hired a private investigator for a year to gather tangible evidences of her husband's unfaithfulness. A close friend of the 29-year-old actress said that Kardashian only wanted to satisfy a clause in the couple's prenuptial agreement. Such clause states that the terms of their financial agreement will change if there is enough evidence that cheating transpired.

"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," added the friend.

If the youngest Kardashian daughter decides to bring everything into court, then her husband might end up paying a hefty amount of cash. While the actress wants to have a baby, sources say that she does not trust her troubled husband and there is no way she will have an innocent life affected by all the circumstances.
