Khloe Kardashian, Rob KardashianOh my. It's no secret that Khloe Kardashian and Rob Kardashian have a super close bond. Out of all the Kardashian-Jenner siblings, they're the closest in age and probably have one of the deepest connections. Rob even lived with Khloe for a spell while she was married to Lamar Odom.

In a Keeping Up With the Kardashians clip, Khloe laments to her step-brother Brody Jenner that she feels responsible for the poison that Lamar brought into Rob's life. The family is vacationing in Thailand without Rob, and Khloe has been debating going home to Los Angeles to be with him.

Rob has been been going through a rough time recently, gaining weight, skipping Kim's wedding to Kanye West, and reportedly getting deep into sizzurp and pot.

Apparently Khloe blames Lamar for bringing that junk into his life and herself for not protecting her little bro. She doesn't specifically mention drugs in the clip, but her ex-husband's infamous drug problems immediately come to mind.

Khloe tells Brody, "Rob has said, 'Being in that house it was so dark and it made me do dark things.'" Brody (rightfully) tells Khloe that she shouldn't feel guilty about what Rob's going through and that she has enough on her own plate to worry about without taking responsibility for Rob's depression.

It's not so easy for "nurturer" Khloe to let it go though. She says, "Only Rob and Lamar know what happened in the house and know what's going on ... I was not there to protect Rob. I was not there to protect myself."

Agghh! Break our hearts already. Khloe may have a mouth on her, but underneath her feistiness, she's so tender-hearted. It is so sweet that she wants to help Rob, but girlfriend does need to learn that no matter what went down when she, Lamar, and Rob were living together -- everyone is responsible for their own actions.
 

Do you think Lamar Odom is responsible for Rob Kardashian's problems?
