Kim Kardashian’s relationship with younger brother Rob came under scrutiny when he skipped out on her wedding to Kanye West in Italy earlier this summer, but Kim is definitely still keeping up with Rob. 

The reality TV starlet took to Twitter to jump to her brother’s defense after his ex-girlfriend Adrienne Bailon revealed he had cheated on her in a recent interview.

Bailon told Latina, "It's common knowledge that he cheated on me… He strategically planned things out so that he could cheat on me, and that to me was so disloyal.” 

She then went on say her appearances on “Keeping Up With the Kardashians” while the two were an item hurt her career. 

"To be stuck with that Kardashian label, that was so hurtful to me and to my career. I probably realized that too late -- not that it would've affected my decisions in terms of who I dated, but it would've affected my decision to appear on the show." 

The jabs didn't sit well with big sister Kim.

Rob Kardashian has recently made headlines for his struggles with his weight and his distance from his reality TV family.
