According to Fantasia Barrino’s manager, the American Idol winner was not responsible for breaking up the marriage of a North Carolina couple, People reports. In a child custody case filing, Paula Cook alleged last week that her husband, Antwaun Cook, and Barrino began a year-long “covert adulterous affair” in August 2009 and allegedly “recorded their illicit sexual activity.” Paula and Antwaun Cook, who have two young children, reportedly split in June. “Fantasia is certain that she is not responsible for the deterioration of [their] marriage,” Barrino’s manager, Brian Dickens, said in a statement released Monday. “Mrs. Cook gratuitously included claims about Fantasia to sensationalize that litigation. Fantasia will weather this storm with the dignity and grace that she has exemplified throughout a life in which she has repeatedly overcome obstacles and challenges.”
