Rob Kardashian has taken a shot at ex-girlfriend Adrienne Bailon on Twitter

Kim Kardashian’s brother - Rob Kardashian, 27,  has taken a shot at ex-girlfriend Adrienne Bailon on Twitter.

The Keeping Up with the Kardashians starappeared to respond to the singer-turned-talk show host's claims that dating him hurt her career by retweeting a message from sister Khloe reading 'FDB' - an abbreviation for slang term 'f*** dat b****'.

Daily Mail reports, Khloe shared the jibe on Wednesday just hours after sister Kim, 33, leapt to Rob's defence and scolded Adrienne for kicking their sibling - who has been battling depression over his substantial weight gain.

The former 3LW singer, who dated the reality star for two years from 2007 to 2009, recently gave a tell-all interview in which she accused Rob of cheating on her and claims that appearing on the famous family's E! show had a negative impact on her career.

 Kim was the first Kardashian to hit back at Adrienne, tweeting: '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.
