Reality TV star Kim Kardashian has hit out at brother Rob Kardashian's ex-girlfriend Adrienne Bailon for bad mouthing her sibling.

Talking to a Latina magazine, the actress-and-singer, who dated Rob for two years, claimed that appearing on her ex-boyfriend's family's reality show "Keeping Up with the Kardashians" did her career more harm than good, reports femalefirst.co.uk.

Kim took to microblogging site Twitter to set the record straight.

"Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is because she is talking about a Kardashian," she wrote.

"So sad when people try to kick my brother when he is down #FamilyForever (sic)," she added.
