CALIFORNIA (Daily Mail): Rob Kardashian has taken a shot at ex-girlfriend Adrienne Bailon on Twitter. The Keeping Up with the Kardashians star, 27, appeared 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’. 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.
