Khloé Kardashian is furious with her friend Adrienne Bailon for branding her younger brother "disloyal."

The 'Keeping Up with the Kardashians' star lashed out at the former Cheetah Girls member, 30, on Twitter after she claimed in an interview that her two-year relationship with Rob Kardashian, 27, had hurt her career.

The 30-year-old beauty tweeted: "Thought her and I were cool SMH (Shake My Head)."

She also retweeted a message from a fan that read: "Adrienne has a lot of nerve to talk s**t about Rob when he is obviously dealing with s**t."

Another fan asked Khloé whether her sister Kim, 33, was "shading" Adrienne when she posted the following tweet earlier today (30.07.14): "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 (sic)."

Khloé responded: "Don't think it was a secret. For sure. Don't kick my brother while he's down."

The famous sisters rushed to defend Rob after 'The Real' co-host Adrienne slammed him for cheating on her and admitted she regretted making cameos on his family's E! reality series before they split in 2010.

She said: "To be stuck with that Kardashian label, that was so hurtful to me and to my career."
