In the newest episode of 'Keeping Up With the Kardashians', Khloe Kardashian claims her estranged husband Lamar Odom's bad influence caused her brother Rob to be addicted to drugs.

"Rob has said, '[Living with Khloe and Lamar] was so dark and it made me do dark things,'" said Kardashian in the promo for the upcoming 'Keeping Up With the Kardashians' titled 'A Thailand Vacation - Part 3.'

"Only Rob and Lamar and I know what went on in that house. I'm a nurturer and I want to protect everyone. I wasn't there to protect Rob. I wasn't even there to protect myself. No one can make me not feel guilty," she continued.

However, according to a TMZ report, an anonymous source told the entertainment website that Rob's current addiction to "sizzurp" and marijuana was not caused by Lamar's bad habits, it occurred as a result of the public breakup between his sister and Odom.

The only son of Kris Jenner and the late OJ Simpson Defense Lawyer Robert Kardashian, Sr was extremely close to Odom, but reportedly after the former NBA athlete was no longer in a relationship with the 30-year-old reality TV star, Odom did not keep in touch with anyone in the Kardashian-Jenner household.

As a result, Rob has not been the same person since his trusted ally is no longer in his life, which reportedly lead to his major drug addiction.

In other 'Keeping Up with the Kardashians' news, there are new reports that claim Khloe is allegedly pregnant with her new rapper boyfriend French Montana's baby.

 'Keeping Up with the Kardashians' Season 9 airs every Sunday at 9 p.m. ET on the E! Network.
