If your name is Jennifer Carpenter you would be wrong. After splitting with her ex, Michael C Hall because he cheated on Jennifer during their marriage, Jennifer has had an affair with a married singer named Seth Avett. A long long time affair. According to Radar, the two have been carrying on for years and just two months ago Seth's wife said everything was great. Yesterday, Seth released a statement that his marriage is over.
