Todd and Kyle Chrisley with Chloe on season 1 of ‘Chrisley Knows Best’

“He grabbed me and choked me when I was pregnant,” Angela tells the mag of Kyle, who was charged with assaulting her in 2013. “There was a time when he got mad at me and came at me with a knife while I was holding Chloe. He was talking about stabbing me, then threw a bottle of pills and hit me and Chloe right in the face with them.”

She also insists Kyle hid his drug use when they were together. “He lies about everything," she says, “but I could tell he was jacked up because he was always just moving around.”

Angela, who shares custody of the toddler with Todd, tells 'Life & Style,' “Kyle is saying he wants Chloe, but he’s really after money.”

Kyle, who admits he was once diagnosed as bipolar, insists he’s now “stable” and ready to parent Chloe with the help of his wife of six months, Lexi.

“She’s a mental case,” Kyle tells 'Life & Style' of Angela. “I don’t want any money. I want my daughter.”
