Los Angeles - Rob Kardashian has "drastically cut back" filming on Keeping Up with the Kardashians.
The sock designer - who failed to attend his sister Kim Kardashian's wedding to Kanye West last month - has reportedly been ignoring calls from his family and has refused to be a part of story-lines on the next series of their reality show.
A source said: "Rob has been holed up in his house, and hasn't been returning calls from concerned family members. Rob made the decision months ago that he didn't want to have a recurring storyline on the upcoming season of 'Keeping Up with the Kardashians' and drastically cut back on filming."
Rob - who is said to be increasingly happy with his body after gaining a substantial amount of weight - feels his mother and manager Kris Jenner is more focused on looking after the business interests of his sisters Kim, Khloe and Kourtney Kardashian and half-sisters Kendall and Kylie Jenner than his endeavors so wants out of the show.
The source added to RadarOnline.com: "Rob feels that the reality show has truly ruined his family, and that momager Kris Jenner is always on the look out for the next big deal for one of her daughters. His significant weight gain has only added to the stress in his life. He has been working out but has very bad eating habits."
