Rob Kardashian's weight gain concerns might finally get its fitting conclusion before sister Kim Kardashian's wedding as the "Keeping Up With the Kardashians" reality star is seriously considering a major stomach surgery to drop off the excess pounds.

Rob Kardashian, who has been gaining weight and battling fat issues, is supposedly mulling the procedure over pressures from momager Kris Jenner to do something about his weight gain.

According to MailOnline, the "Keeping Up with the Kardashians" star was said to have tipped the scales at 260 pounds. After Rob Kardashian's weight gain of at least 70Ibs, momager Kris Jenner apparently laid down an ultimatum to the 26-year-old.

Meanwhile a source told National Enquirer that Rob Karashian, despite his best intentions, "hates gyms."

"But he's under strict orders from Kris to lose 70lbs before Kim's wedding to Kanye West this summer," the source said, adding that the only way for the reality star to lose that much weight in so short a period of time is "getting his stomach stapled."

The publication added that Rob Kardashian was supposedly not satisfied by the progress of his diet and exercise to reverse the weight gain.

"This procedure is a major operation. But being the ugly duckling in the family has affected Rob deeply. Everyone's worried about him," the Enquirer added.

The Star earlier reported that Kris Jenner has been very harsh of her criticisms over Rob Kardashian's weight gain.

"She called him a fat slob and said he's losing out on business opportunities because no one wants someone as huge as him representing their products," the source told Star.

Kris Jenner also suggested that the sock entrepreneur should enroll himself on a "fat camp" because his weight gain has caused an embarrassment to the family. The news website added that the other Kardashian sisters, Kim, Khloe and Kourtney were supposedly behind their mother since they are also "embarrassed to be photographed with him."
