Rob Kardashian, the younger brother of Khloe Kardashian, has reportedly known about Lamar Odom's alleged drug addiction for more than a year and is currently staying at the couple's California mansion, according to the latest reports.
"[He has] known about Lamar's drug addiction for over a year. How could he not as he has lived under the same roof with Lamar and Khloe? Rob even spent a significant amount of time with Khloe and Lamar when he was traded to the Dallas Mavericks," a family insider told Radar Online of the rumors.
Unconfirmed reports have stated that Odom has been allegedly addicted to the painkiller OxyContin and sleeping agent Ambien for at least a year.
"Rob isn't a party animal like Lamar, and drugs just aren't his scene. The two used to be very close, but have drifted apart because Lamar has been abusing Oxy and cheating on Khloe. Rob has continued to live at the Tarzana mansion to support Khloe, he really has her back," the source claimed.
It has been reported that Kris Jenner has been "acting as the de facto marriage counselor and mediator between Lamar and Khloe," a source told The Hollywood Gossip. However, neither Kardashian nor Odom have addressed the divorce and drug rumors publicly, allowing speculation to run rampant.
"Khloe kicked Lamar out of their home several weeks ago and he has been living in different hotels. Kris believes that Lamar has a lot of unresolved issues surrounding his childhood and he needs to work through it," an insider claimed.
While the celebrity couple has had a difficult past couple of months, Kris has been vocal in her support of Khloe while advising her to fight for her marriage.
"She is encouraging Khloe not to give up on her marriage and not file for divorce … Khloe hasn't been able to forgive him yet, but a divorce likely won't happen," the insider added.
