'16 and Pregnant' Star Whitney Purvis' Son Weston Dead at 16

Weston Gosa Jr. — the son of “16 and Pregnant” star Whitney Purvis — has died … according to a message posted by Whitney to Facebook.

The former teen mom shared the sad news Monday … sharing a photo of the two smiling. Whitney has her arms wrapped around her son in the sweet snapshot.

She captioned the photo, “Rest in Peace, my baby Weston. I love you forever, precious. I’ll never understand why life has to be so cruel. You’ll always be my baby.”

Whitney did not share a cause of death in the post … but, Weston’s stepmom, Amy Gosa, also posted about Weston’s passing — telling fans they tried to wake him up at 7 AM today and couldn’t.

Amy says they tried CPR and called an ambulance. Paramedics rushed Weston to a local hospital where he was pronounced dead.

The family is waiting on autopsy results, Gosa says … but, she adds Weston had a number of medical issues, including diabetes.

Weston was born back on April 2, 2009. Whitney was actually pregnant with him when she and her baby daddy — also named Weston — were on the show’s inaugural season way back in the day.

Purvis lost custody of Weston and her other son, River, in the years since leaving the show … and, she was arrested last year for allegedly failing to make child support payments.
