Rob Kardashian is still on the vengeful path against his mother this 2015, at least according to a tabloid which claimed that the reality star who's currently battling weight gain is reportedly planning to call the cops on Kris Jenner for allowing her underage date a 25-year-old man.

The report was referring to 17-year-old Kylie Jenner who's currently dating rapper Tyga, who has a son with Blac Chyna.

According to Celebrity Dirty Laundry, Rob Kardashian has been battling weight gain and addiction over the past year.

"The Keeping Up With The Kardashians star blames his momager Kris Jenner and sisters for his problems. And the fact that they are exploiting his issues and using the as storylines on their family's reality TV show are only infuriating Rob more. Rob Kardashian is determined to take down his family and make them pay - literally," it said.

Reportedly, Rob Kardashian is planning a lawsuit this 2015 to stop the "KUWTK" show from using him and his weight gain as a storyline. If the reports are true, the sock mogul is also looking to cash in by the millions in the civil aspect of the lawsuit.

"Not only is Rob threatening to take his family to court and sue them over dragging his name through the mud on KUWTK, but he has also been selling stories to the press about his family, and plotting to give a tell-all interview," the report claimed.

Although Tyga dating Kylie Jenner is technically illegal in California, the police won't come in unless a family member calls Child Protection Services.

Sources told CDL that Rob Kardashian is on the warpath this 2015 and is using the Kylie Jenner situation to blackmail his mother into folding in from his demands.

Kylie Jenner and Tyga have not directly confessed that they are dating, which makes sense because she won't turn 18 until August.
