PHILADELPHIA — Valerie Fairman, 23, who starred on the second season of MTV’s “16 and Pregnant,” has died.

The Oxford, Pa., native was pronounced dead Wednesday afternoon at Brandywine Hospital, the Coatesville Police Department confirmed, after a call was made about a possible overdose.

The Chester County Coroner’s Office confirmed the investigation into the exact cause of death is still ongoing, but TMZ reports from sources say that Fairman died of an overdose.

Fairman’s substance abuse issues were documented on her 2010 episode of MTV’s “16 and Pregnant.”

Fairman’s daughter, 7-year-old Nevaeh, is with Fairman’s mother, TMZ reports.

In 2015, Fairman was arrested for prostitution in Delaware, along with seven other women.

In 2010, Fairman and her then-boyfriend, Matt, were featured on the second season of “16 and Pregnant,” the forerunner to MTV’s popular “Teen Mom” series that came to define the network in its reality-TV heyday.

Episodes, running from 2009 to 2014, focused on young women who became pregnant; the subsequent “Teen Mom” followed them through early motherhood.

“We are saddened by the news of Valerie Fairman’s passing,” an MTV spokesperson told Variety. “Our thoughts and prayers are with her family at this time.”
