Eric “The Actor” Lynch, a regular on Howard Stern’s SiriusXM radioshow, died Saturday, according to his manager. He was 39.

According to TMZ, Fratto said Lynch was rushed to a Sacramento hospital on Saturday after he began to have heart problems. He died in the hospital, surrounded by family and friends.

No official cause of death has been announced yet.

Lynch, also known as “Eric the Midget,” began calling Stern’s show in 2002, and quickly built up a reputation among those on the show and fans for yelling at the host. He would become a part of Stern’s “Wack Pack.”

Most recently, he called the show last week and informed listeners that his parents were taking over caretaking duties from his manager. Lynch was plagued by various health conditions, which he often updated the show about, but claimed he outlived doctors’ predictions on his life expectancy. He was three feet tall, and used a motorized wheelchair for transportation.

Lynch also had several television credits, including guest spots on “Fringe,” “In Plain Sight” and “American Dreams.”
