After reading what her co-star had said, Lowell fired back on Twitter.

Also weighing in on Twitter was Ambert Portwood, who shrugged off their weekend video.

Meanwhile, Lowry spoke to Real Mr. Housewife, reminding Abraham about her past career decisions.

“What was said was said but there’s no reason to bring parenting into it,” Lowry explained. “To call anyone a pathetic parent is a low blow. Farrah has done porn, and anytime anyone has asked me to comment I say whatever works for her and pays her bills.”
