Khloe Kardashian Worried About Rob Kardashian's Hard Partying And Drug Use: Report

Though they are allegedly at odds at the moment, Khloe Kardashian is reportedly concerned about the health of her kid brother, Rob Kardashian.

According to Hollywood Life, a source has revealed that Khloe, 30, is very worried about her brother and his hard partying. Her concerns reportedly increased after TMZ released photos showing Rob, 27, partying and holding a cup labeled “Codeine Boys” – referencing a mix of codeine cough syrup and Sprite soda known as “lean.”

With recent reports of Rob’s excessive drug use and depression, the source says Khloe can’t believe the problems her brother is facing.

“Khloe can’t think right now; she’s just in disbelief right now that her little brother is going through these issues. She realized he’s been troubled for a long time now, but was in the dark that it’s reached this level,” the source told Hollywood Life. “She can’t deal. She feels low because she’s been through this before with her ex [Lamar Odom], and it’s all too familiar and another earthquake that’s rocked her core.”

Adding to the difficulty of the situation, Rob has reportedly ceased communication with both Khloe and his sister Kim Kardashian, following his blowout with Kim ahead of her wedding to Kanye West.

According to Radar Online, a source says Rob “has no reason to talk to Kim” and the siblings “haven’t been on good terms for a very long time.”

Kim “hasn’t bothered to even attempt to talk to him since returning from her honeymoon, [while] Khloe has sent him text messages and left him several voice mails,” the source told Radar. “Rob hasn’t returned any of Khloe’s phone calls or texts. He feels completely estranged from his sisters and family. He really isn’t in a good place.”

A source told Hollywood Life that Khloe has attempted to reach out to her brother, but Rob will not return her calls.

Rob has faced a trying last few months, with the talk surrounding his weight and his sudden departure from Kim’s wedding party. After returning to Los Angeles from Paris in June, he cleared his entire Twitter account and unfollowed several of his family members. However, he has since returned to social media.
