Big, Fat Liar! How Blac Chyna Fooled Rob Kardashian Into Re-Packing On The Pounds

Rob Kardashian has packed on a whopping 30 pounds of sympathy pregnancy weight alongside his expecting wife-to-be, Blac Chyna — and she now fully intends on keeping him plumped up!

"Chyna has decided skinny Rob is no good," explained an insider.

The reason is simple — and a bit sinister: "She likes him portly because that's when he lacks confidence, making him easily controlled," revealed the insider.

Blac, 28, relaxing her rules on 29-year-old Kardashian's fitness routine is an about face from the beginning of their relationship, when she put him on a strict diet and exercise regimen.

"When he lost weight earlier on, he hit the party scene and she's convinced he got way too close with a string of strippers," said the source.

"She's been subtly encouraging him to 'treat himself' now that they're approaching her due date, and while she's already planning a post-baby weight-loss blitz, she's making sure Rob won't be doing the same."
