WATCH: Kim Kardashian Mocks Rob Kardashian’s Weight Gain

Low blow Kim.

For the last few years, Rob Kardashian has been struggling with his weight and health issues including depression and most recently diabetes, but that hasn’t stopped sister Kim Kardashian from getting a laugh as his expense. During last night’s (Jan.3, 2016) episode of Keeping Up With The Kardashians, the family begins talking about tattoos while on vacation in St. Barths after it is revealed that Tyga tattooed Kylie Jenner’s name on his arm.

Tyga explains that his tattoos tell a story and that every tattoo has a meaning. Kris Jenner chimed in, saying Rob feels the same way about his tattoos, but Rob’s sisters can’t help but trash talk his ink. “Rob’s stupidest tattoo is when he got Adrienne [Bailon] and then covered it with Rita [Ora],” says Kylie, before Kim adds, “He covered it with a life-sized Barbie doll of Rita that has now turned into a Cabbage Patch. Have you seen it lately? It was a Barbie doll, and he has gained weight, [now] she’s like a huge Cabbage Patch.”

Ouch.

While Khloe Kardashian looks visibly uncomfortable, Kris and the rest of the family laugh at Kim’s insensitive joke. Launch the video up top to watch the entire exchange.
