Khloe Kardashian, Lamar Odom Cheating Scandal Grows, Mistress Claims Proof of Affair

In the wake of reports that Lamar Odom cheated on Khloe Kardashian, the alleged mistress is claiming that she has proof of their affair.

The alleged mistress, Jennifer Richardson, is claiming to have several items proving she and Odom were involved in a relationship for several months.

Richardson is thought to have plane tickets, invoices and game tickets from her time on the road with Odom between December 2012 and February 2013, when Odom played for the L.A. Clippers, a source told Radar Online.

He also allegedly put her up in five-star hotels, using his friend, Anthony McNair, as an alias.

Unconfirmed reports indicated that Odom has been allegedly cheating on his wife since at least January 2012. He was with 29-year-old Jennifer Richardson after the two met while Odom was a member of the Dallas Mavericks and was in Washington D.C. for a game against the Washington Wizards.

Kardashian had previously stated that divorce was never an option and that she was willing to work through any problems to keep their marriage intact.

This is also not the first time it was reported that Odom moved out of their house.

Last September it was claimed that Odom, who is now playing with the Los Angeles Clippers, moved out of their marital home due to their alleged marital woes. It was also said that Kardashian's new "X-Factor" gig prompted divorce talks.

"The only thing Lamar has been sticking around for was a child," a source reportedly told Star magazine at the time. "But since Khloe hasn't been able to get pregnant, he doesn't see any point in staying in the marriage. He's done."

The source later confirmed that Odom never moved out of their Los Angeles home and the couple, who had recently celebrated their anniversary, was stronger than ever.
