Kris Jenner visited Rob Kardashian's pad after the former "KUWTK" reality star missed her 60th birthday celebration, according to the latest news reports in the momager-sock mogul saga this 2015.

"On Tuesday Kris Jenner was snapped pulling through the security gate at her son's pad," said X17online.

Apparently, Rob Kardashian moved back to his apartment this 2015 after hiding for months in the mansion of his sister, Khloe Kardashian, while his weight ballooned to over 300 pounds.

"Rob hasn't been seen out much lately, but based on social media and various online reports, he has been hitting the gym and going on hikes with his family," it said.

Rob Kardashian's fluctuating weight can become its very own reality show owing to the number of attention it generated from the tabloids this 2015. But the latest news reveal that it appears as if the sock mogul is intent on dropping the extra pounds because of a huge incentive.

"He's not getting paid if he doesn't film," a source told Us Weekly. "He has a $2 million-a-year contract. He realized he couldn't give up this huge opportunity."

Rob Kardashian is already filming scenes last September for new episodes of "KUWTK," the magazine added.

Meanwhile, the visit from momager Kris Jenner could be prompted by the fact that Rob Kardashian missed her 60th birthday party.

"Reclusive Rob Kardashian appeared to have sat out the Gatsby-eque 'Roaring 20s' party, despite being named as host alongside his sisters," said Daily Mail.

"As close as he is to his mom - Rob even has Kris' portrait tattooed on his arm - it would have been a huge surprise to see him attend," the tabloid added. "Since dropping out of the limelight, Rob has missed many a family occasion due to the attention associated with any gathering of his sisters."
