Rob Kardashian reportedly told his mom, Kris Jenner, to butt out of his life. It seems there’s never been much love lost between the two, and sources say Rob even blames Kris Jenner for his weight gain.

“Kris was always focused on the girls,” a source told RadarOnline. “It always bothered him, and he filled the pain with drugs and alcohol.”

Rob Kardashian desperately wants to shed some of the weight he gained over the past year or so–and he gained a lot. Since he’s made that wish known, Kris Jenner has tried to connect with him. She now seemingly wants to support her only son.

“Kris offered Rob a place to live and wanted to work on their relationship, but he turned the other cheek and is living with his sister, Khloe,” the source said.

Khloe Kardashian is the mother figure for the entire Keeping Up With the Kardashians family. When Bruce Jenner was involved in a fatal car accident almost a week ago, it was Khloe to whom Kendall Jenner ran for solace when worried about her dad.

Fortunately Rob Kardashian has Khloe to turn to, in light of the notion that Kris Jenner has long doted on Kim Kardashian and her sisters Kourtney and Khloe, as well as Kendall and Kylie Jenner–sort of leaving Rob in the dust. It seems like the girls served to make her money with the reality shows, but Rob was the family’s black sheep.

“Rob is struggling, but he’s trying his best to get his muscular body back—and he’s told Kris that he’ll be doing it without her help,” the source said.

Hopefully Rob Kardashian achieves his weight loss goal and emerges with both a healthy body and a healthy mind.

Do you think the relationship between Rob Kardashian and Kris Jenner will ever be that of a loving mother and son?
