Kim Kardashian gets raunchy for Rolling Stone and admits the truth about her brother Rob

Well, ahoy there sailor! Kim Kardashian took naughty nautical to the next level for this month's issue of Rolling Stone.

But it's not the raunchy cover which has even one talking but the fact she finally broaches the subject of Rob, who has gone into hiding since piling on the pounds.

"He has gained weight. He feels uncomfortable being on the show, and that’s OK," she said.

"Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."

We can already sense another biting Instagram from the recluse, who compared Kim to Gone Girl psycho Amy earlier in the year.

It's been years since Rob has made any formal public appearances, even fleeing Kim's wedding back in 2014 when the pair had a show down about his weight.

And 34-year-old Kim has been honest in previous interviews about how she's the only family member not to "lick his arse" and speak the truth.

She explained to Rolling Stone: "I think I'm just more of the tough love kind of person. My personality is like, 'All right, you complain, you don't like it, get up and do something about it.'"

But despite her tough love, it doesn't look like Rob's sad situation is going to resolve itself any time soon.
