She was 26.
A spokesperson for Maryland’s Office of the Chief Medical Examiner confirmed Cashmyer’s death to CNN. No cause of death had been made public as of Monday.
Cashmyer appeared on the MTV series in 2014 with her then boyfriend Derek Taylor.
The couple were shown dealing with unemployment, homelessness and family disapproval as they awaited the birth of their daughter, Genevieve “Evie” Taylor.
MTV’s verified Twitter account for the show “Teen Mom,” which is a spinoff of “16 and Pregnant,” offered condolences.
“We are deeply saddened to learn about the passing of Jordan Cashmyer,” the tweet read. “Our hearts go out to her family and friends during this difficult time.”
