The (New Orleans) Times-Picayune said Candy Edwards, 45, suffered a cut to her forehead and a broken tooth in the alleged dispute that landed Brian Low in jail on a $200,000 bond.
Low, who has a 3-year-old son with Candy Edwards, is facing a felony second-degree battery charge after being arrested Sunday.
An East Baton Rouge Parish Sheriff's Office arrest form said the "victim stated that she was arguing with the accused when he grabbed her by the neck and threw her against the wall in a bedroom."
Low's arrest form also alleges the 34-year-old punched Candy Edwards in the face, breaking one of her front teeth. Low denied punching Candy Edwards in the mouth during the incident.
The Times-Picayune said Low told a deputy he and Candy Edwards, who divorced Edwin Edwards in 2004, have been separated for nearly three months.
