Well, that is if you think Nas' former girlfriend & baby mama, Carmen Bryan. She did a question & answer session with her fans on Twitter a few days ago, and spilled everything. She claimed the feud between Jay Z & Nas started after she dated & got pregnant for Jay Z. She said she later lost the pregnancy. The feud between Jay Z and Nas (from 2000/2005) was one of the most followed feuds in hip hop history.
Carmen also claimed Nas' ex-wife Kelis is bisexual and they once asked her for a threesome. See the tweets after the break...
