After just one year of marriage, Amber Rose has filed for divorce from rapper Wiz Khalifa. Rose cites irreconcilable differences, and there is apparently no mention of infidelity in the divorce papers, despite rumors about an affair between Rose and Mariah Carey’s ex Nick Cannon. Khalifa and Rose have a son, Sebastian. Rose is asking for full legal and physical custody of the boy. On Thursday, Rose confirmed the divorce, tweeting, "Please stop with the fake stories. I would never ever ever cheat on my husband in a million years I think u guys know this....." and then "Unfortunately my now ex husband can't say the same…."
