Kim Kardashian shut down rumors that she and Rob Kardashian don't get along amid his weight issues when she slammed his former girlfriend on Twitter in his defense.

Khloe Kardashian Blames Herself For Rob Kardashian's Issues

Kim came for Adrienne Bailon and put her on blast after Bailon did an interview with Latina magazine and claimed being with Rob tainted her career. She also said Rob was "disloyal" and unfaithful several times in their relationship.

Kim caught wind of the interview and wrote, "Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is bc she is talking about a Kardashian...#LetItGooooooLetItGoooooo...So sad when people try to kick my brother when he is down #FamilyForever".

Khloe Kardashian also chimed in on her own Twitter and reposted Kim's messages.

She went on to suggest she's disappointed by Bailon's words and added, "thought her and I were cool SMH".

Khloe also defended Kim's tweets after a fan asked if Kim was throwing shade on Bailon.

Khloe wrote, "Don't think it was a secret. For sure. Don't kick my brother while he's down."

Khloe and Kim's comments come just after Bailon told Latina in its September 2014 issue, "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. At the time, I didn't think anyone would even care. To this day, people will still say, 'You ruined Rob's life!' and I'll think, 'I was still playing with Barbie dolls when I met him.'"

She also revealed that Rob was very "strategic" in cheating on her and being "disloyal."
