There is a new reports that claims that Keeping Up With the Kardashians star Rob Kardashian is allegedly addicted to weed and "sizzurp".

According to TMZ, multiple insiders told the entertainment news company that the family is attempting to convince Rob to go drug rehab in order to cure him of his supposed drug addiction. Unfortunately, according to the report, he refuses to get help from his family or anyone.

TMZ also posted photos of the 27-year-old reality star holding a cup believed to contain Sizzurp inside a container titled "Codeine Boys" at a wild party filled with drugs and alcohol.

According to the New York Post, Sizzurp (aka Lean) is created by mixing Sprite (or Mountain Dew) with cough syrup medicine that has codeine and promethazine as ingredients. In addition, Jolly Rancher candies are sometimes included into the dangerous drink.

In addition, the lone son of the late lawyer Rob Kardashian Senior and Kris Jenner was also seen reportedly smoking marijuana at the party a few days ago.

The famed family wants to intervene on Rob's behalf, but apparently, he has not spoken to his sisters Kim and Khloe since he decided not to attend Kim and Kanye's much publicized wedding last month.

"[Rob] has no reason to talk to Kim," said an unidentified insider to Radar Online, "They haven't been on good terms for a very long time."

The source provided further insight into the current relationship between Rob and two out of his three sisters.

"[Kim] hasn't bothered to even attempt to talk to him since returning from her honeymoon, [despite the fact] Khloe has sent him text messages and left him several voice mails," the anonymous insider continues, "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."

In addition, Khloe went on social media in order to reach out to her brother Rob in his time of need.

"I miss my best friend @robkardashian,♥" wrote Khloe via Instagram to her sibling Rob two weeks ago.
