Updated at 8:30 p.m. ET: LOS ANGELES -- Veteran pornography actor Ron Jeremy, one of the industry's biggest stars, was in intensive care and undergoing surgery for an aneurysm near his heart in Los Angeles, his manager said on Wednesday.
Jeremy, 59, the star of more than 2,000 adult films, drove himself to Cedars-Sinai Medical Center in Los Angeles early on Wednesday after suffering from chest pains.
"He just felt chest pains, like a very heavy weight," Jeremy's manager Mike Esterman told Reuters.
Jeremy's medical team later released a statement via Esterman to E! News saying the surgery went "smoothly" and that the adult film star was "resting with complete privacy."
Jeremy, nicknamed the "Hedgehog" for his short and hirsute body and known for his large mustache, parlayed his porn star fame into mainstream celebrity status by appearing on the American reality television series "The Surreal Life" in 2004, and by being featured in an advertisement by animal-rights advocates PETA.
His memoir, "The Hardest (Working) Man in Showbiz," was published in 2007.
