The 'Keeping Up with the Kardashians' star is said to be furious that her husband of four years has been accused of having affairs with two different women and told him he must prove himself to her, reported Contactmusic.
"Things have never looked worse but Khloe wants to know the truth and if it means getting Lamar to do a polygraph test then so be it. Lamar is appalled and totally offended by the idea.
"Every time she starts grilling him, Lamar hits the roof and accuses her of not trusting him. Then he just clams up or hangs up. He hates confrontation," a source said. According to reports, Odom cheated on her with Jennifer Richardson for a year until March 2013 and also had a six-week long affair with lawyer Polina Polonsky at the start of the summer.
