Khloe Kardashian proves to be one loyal big sister and is now defending her brother Rob Kardashian against ex-girlfriend Adrienne Bailon.

According to US Magazine, Khloe first backed up her sister Kim's comments on the matter via Twitter. The retweeted post read as follows: "So sad when people try to kick my brother when he is down #FamilyForever... 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."

KK then followed up on Kim's defense by making her own comments about the issue.

She retweeted some other fans while accompanying it with her own thoughts. Some of her retweet comments include "Thought her and I were cool SMH" and the other one was "Don't think it was a secret. For sure. Don't kick my brother while he's down."

The defense of the Kardashian clan all became more evident just 24 hours after the revealing interview of Bailon was published on the Latina Magazine September 2014 edition.

In the interview piece, the former Disney star bashed her ex Rob Kardashian for cheating troubles and even said that her inclusion in the "Keeping Up With The Kardashians" show eventually caused her career more hurt than benefits in the long run.

People Magazine recalls that it has been five years since Adrienne and Rob were together and now the 30-year-old singer-actress regrets how she has gotten connected with the elite clan in the public eye.

"To this day, people will still say, 'You ruined Rob's life!' and I'll think, 'Damn, I was still playing with Barbie dolls when I met him," Adrienne said.

Meanwhile, Rob Kardashian finally had his say on Adrienne's bashing and other revelations about him. The Kardashian brother simply retweeted his older sister KK who wrote "FDB" which is a slang rap term for "F--- Dat B----."

A source shared with Hollywood Life how Rob has been resenting how his family's reality show has been allegedly capitalizing on his weight problems.

This is one of the reasons why many think Rob is isolating himself from the family especially from his famous sisters. He is rarely seen in the show's current season and he has not explained the reason for his absence ever since.

KK reportedly feels sorry for Rob while Kim thought that he needs to be treated with tough love as an adult.
