Adrienne Bailon isn't done talking about the Kardashians

A day after Kim and Khloe blasted the singer for dissing their family, Adrienne took to Instagram to defend her comments. Adrienne, who dated Rob from 2007 to 2009, wrote, "Fame and career are two different things. I've always had a career. I have been working hard since I was 15 years old. Being someone's 'girlfriend' was never what I wanted to be famous for. What makes you 'famous' isn't always what you want to be 'labeled' as, or known for. If anyone should understand that…It should be you."

Things got nasty when Adrienne said in an interview with Latina magazine earlier this week that appearing on the Kardashians' reality show hurt her career. She also accused Rob of cheating on her.
