Kardashian family's fear
Rob Kardashian's family are reportedly "concerned" about his well-being.
The 'Keeping Up With The Kardashians' stars - which include matriarch Kris Jenner and Rob's siblings Kim, Kourtney and Khloe - are said to be worried about how the 28-year-old sock designer is coping with his girlfriend Blac Chyna's recent arrest for drug possession.
A source told PEOPLE magazine: "[At first], it seemed Blac Chyna was really encouraging Rob to stay healthy and clean. But her arrest is changing things. The drug possession is very concerning.
"No one wants Rob to live with someone who does drugs. If [Blac Chyna] isn't helping him, Rob's family won't tolerate it."
Meanwhile, sister Khloe is feeling "betrayed" by Rob's new romance.
An insider said previously: "Rob is living with Blac now that Khloe kicked him out after finding out about him and Blac. Khloe feels majorly betrayed by Rob after she always stuck up for him. She feels like this is a major blow to the family. Nobody in the family likes it."
However, a source has claimed Rob is getting a "kick out of all the drama that he is causing".
They added: "Rob has been lonely for so long, so of course it's great for him to spend time with someone other than his sisters. Rob has also found an escape from his family nagging him about his health. He has ignored their attempts to contact him.
"Rob likes her and seems to think it's mutual. It's just hard to take things seriously since obviously both share a lot of anger toward the [Kardashian-Jenner] girls. They have both had a lot of drama with Kim. Rob really seems to get a kick out of all the drama that he is causing."
