Kardashians poke fun at Rob's weight in 'Keep Up With Kardashians' clip

Well this was some mean foreshadowing!

Kim Kardashian and her brother, Rob Kardashian, have butt heads many times over the years, and it appears that little has changed.

WATCH: How 'KUWTK' foreshadowed Rob's health struggles

In the upcoming episode of "Keeping Up With the Kardashians," Kim, her sisters, Kourtney and Khloe Kardashian, and their mom, Kris Jenner, all gang up on Rob, who's not with them. They decided that the 28 year old's worst ink was the portrait he got of Rita Ora, the British singer he dated for a short time in 2012.

Kim then went in for the kill with a double whammy diss that knocked both the tattoo and Rob’s weight gain.

“He covered [Adrienne's name] with a life-sized Barbie doll that has now turned into a Cabbage Patch,” Kim joked, causing Kris to giggle as well. “Have you seen it lately?”

WATCH: Rob reportedly hospitalized with diabetes

Kim says that as her brother gained weight, Tattoo Rita also got larger. "She's like huge!" she said laughing.

Rob got the Rita artwork to cover up the name of another ex-girlfriend, Adrienne Bailon, which was inked on his left rib cage. The two dated from 2007 to 2009.

Since that episode of "KUWTK" was filmed, Rob was reportedly diagnosed with diabetes after he felt ill after Christmas and was hospitalized.

WATCH: Kim calls Rob's behavior pathetic

Rob's weight issues, along with his family's concern for his health, have long been documented on the reality show. In 2013, Rob revealed he had gained 40 pounds after his breakup with Rita, and in an episode that aired in April 2015, Kris claimed her son had gained 100 pounds in just one year. She feared he was "gonna die" if she didn't "help him do something drastic.”

Khloe and Kourtney have both showed their support for Rob on social media, sharing throwback photos on Instagram. Kim, however, did not join in on the nostalgia. She's been the harshest critic of Rob amongst his five siblings, though she did defend him against Adrienne last year,and in April joined her brother on "the hardest hike ever," which gave a little hope that they might be mending their relationship.
