Ron Jeremy is fighting for his life at a Los Angeles hospital and is being treated for an aneurysm near his heart.

The world's most celebrated porn star drove himself to Cedars-Sinai hospital on Tuesday after experiencing severe chest pain, TMZ reports. His manager, Mike Esterman, told the site that his condition has worsened after doctors discovered the aneurysm and he was transferred to the intensive care unit.

Jeremy, 59, was being prepped for surgery this morning. It's yet unclear what led to the chest pain.

The adult film actor, who has starred in more than 2,000 films -- pornography and non-porno -- has been an outspoken opponent of the new law in Los Angeles that would require adult film actors to wear condoms while filming . He campaigned against Measure B in the weeks before the election.

He was also reportedly recruited last year to help catch Luka Magnotta, the alleged porn-star-gone-Canadian cannibal.
