According to Radar Online, Kardashian, 29, was shocked to hear the 33-year-old basketball player's confession about sleeping with women without using protection. 

Kardashian "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," a source told Radar. "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 added that the reality star immediately went to the doctor to get checked out and was "tested for a full range of sexually transmitted diseases."

Fortunately for Kardashian, all her tests came back negative. 

"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 just disgusting."
