*Khloe Kardashian regrets the time her brother Rob spent living with her ex-husband Lamar Odom, and says she feels guilty for not being able to protect Rob from Lam Lam’s influences.

According to TMZ, Rob had gotten deep into sizzurp and weed, and his family was pushing for him to go to rehab.

Now, Khloe is insinuating that Rob’s problems stem from the time he lived with Lamar, who has serious drug problems of his own.

“Rob has said, ‘Being in that house it was so dark and it made me do dark things,'” Khloe said on “Keeping Up with the Kardashians.”

Khloe added, “Only Rob and Lamar know what happened in the house and know what’s going on.”

Khloe says she feels guilty about Rob’s situation: “I was not there to protect Rob. I was not there to protect myself.”
