The stars of Teen Mom have had their fair share of controversial parenting moments through the years, involving everything from drug use to sex tapes. Farrah Abraham is one of the TM mothers who often makes headlines for her questionable parenting decisions regarding her eight-year-old daughter Sophia.

Just last year, the 25-year-old defended Sophia's right to wear a full face of makeup — she even had a full-blown argument with her school's principal about it. "There are bigger things to worry about," Farrah told Soph's principal.

"You know, when your kids are five or six they already start playing with makeup, and I was the only mother in freaking elementary school getting called in to deal with makeup on her daughter,” she recalled.

"So I said to them — and I proved my point because then the principal switched schools — I go, 'Well then you should take off your makeup. If you don't want little girls coming to school with makeup then don't wear makeup.' And then ever since I've seen that principal she hasn't had makeup on her face."
