Don't mess with a Kardashian…apparently

Kardashian sisters stand up for brother Rob.

Kardashian sisters have come together in force on Twitter and defended their brother Rob Kardashian from comments his ex-girlfriend - former 3LW singer - said in a recent interview.

Ardienne, who dated the reality TV 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 as a singer and actress.
