Kim Kardashian's brother has reportedly jet to fat camp in a bid to lose weight for her wedding.

The reality star's 27-year-old brother has garnered unflattering headlines for his weight gain.

Reports emerged last month the TV star’s mother, Kris Jenner, had demanded he enter a facility to shed the pounds before Kim's wedding to fiancé Kanye West this May.

And MailOnline now claims Rob, tipping the scales at 260lbs, conceded and entered treatment this week.

According to the website, Kris was seen boarding a private plane in Los Angeles on Monday to take Rob to an undisclosed facility.

A purported insider is said to have told X17 photographers where they were headed.

A spokesperson for the family has yet to issue comment.

Kris apparently asked Rob to register for a fat camp to help him shed nearly a fourth of his body weight.

The National Enquirer previously reported Rob had also considered going under the knife in order to slim down.

“Rob hates gyms. But he's under strict orders from Kris to lose 70lbs before Kim's wedding to Kanye West this summer.

“Rob figured that getting his stomach stapled is the only way to meet Kris' deadline,” the purported insider said.

While the reality personality is said to be dealing with personal struggles, his sister Kim is still catching her breath after landing the cover of US Vogue with Kanye.

The couple sat for a shoot with their daughter North, causing many to scoff at editor Anna Wintour’s decision to feature the divisive couple on the fashion bible.

Kim called the opportunity a “dream come true”.
