They didn't talk abou the baby mama thing, but KRS-1 said it on the special "Fact hurts more than the mess talking", and all I know is that the girl works at Rocafella and that is the exact reason why Jay-Z got with her cause she was Nas baby mama.
Even though it's known she "been around" in the industry, I respect Nas because he went on the radio and said "I don't think Jay should have put her in it, she's still my baby's mother and she should be disrespected like that".
Once again, Go Nas!
