Kim Kardashian mocks her brother's weight: Sibling banter or far too brutal?

Kim Kardashian wasn’t the only one mocking brother Rob’s weight gain on a recent episode of Keeping Up With The Kardashians, but she is definitely responsible for delivering the zinger.

Sisters Kourtney, Khloe and Kylie, as well as mum Kris, were part of it too, joking and laughing at poor Rob’s expense during a vacation in St. Barts.

The conversation started with Kylie talking about her first red love heart tattoo and her rapper boyfriend Tyga discussing his own. The family then begin talking about brother Rob’s tattoos during a family dinner. They debated which of his tattoos is the “stupidest”, describing how he covered a tattoo of ex-girlfriend Adrienne Bailon with ex-girlfriend Rita Ora’s name.

It all goes downhill from there.

Kim — who should know better considering what she has to deal with when it comes to comments about her own weight — says, “He covered it with a life-sized Barbie doll of Rita that has now turned into a Cabbage Patch Doll.”

They all laugh and then she adds, “Have you seen it lately? It was like a Barbie doll and he’s gained weight and it’s like a huge Cabbage Patch Kid. Huge!”

Ouch.

It’s what siblings do, right? We poke fun at each other with little or no filter and are genuinely surprised when we accidentally take the rivalry a step too far and actually hurt each other’s feelings. My own brother and I mock each other constantly and have come to expect it from each other.

Kim Kardashian and brother Rob seem to have a similar relationship. The problem is that Rob has made it known that he is sensitive about his weight gain, and the comments his family made about him were made on a TV show watched by millions.

It’s understood that the conversation was filmed before Rob’s recent health scare over the holidays. The Kardashian brother was rushed to hospital between Christmas and New Year, thought to be due to complications from Type 2 diabetes. Reports state Rob was suffering from “severe stomach problems and diagnosed with diabetic ketoacidosis”.

Since gaining weight, Rob has become reclusive and rarely appears in public. The family is said to be concerned about Rob’s mental and physical well-being and will hopefully be more sensitive going forward. Rob is yet to comment on the situation.

As those of us with siblings know, it doesn’t take much to go one step too far when making fun of each other, and nothing hurts more when it happens in your absence and the joke is on you.
