Khloe Kardashian reportedly got tested for sexually transmitted diseases after hearing about her husband's alleged cheating.
The reality TV star is said to have been tested earlier this year after claims Lamar Odom had been unfaithful during their marriage without using protection.
An insider told RadarOnline.com: ''Lamar refused to admit to how many women it was, but Khloe knew it was at least five different women in the past year.
''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 just disgusting.''
It is said the basketball star - who was reportedly spied on by a private investigator hired by his wife - admitted he ''didn't use protection'' when he allegedly cheated.
The source added: ''[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.''
