"She found out back in May, and broke up with him," an insider told RadarOnline.com of the tumultuous romance. "They were on and off after the scandal."

RadarOnline.com first reported Cartwright and Taylor's split over the summer .

"Brittany was fed up," a source told RadarOnline.com in August. "He didn't treat her right."
