Legendary porn star Ron Jeremy is in critical condition in a Los Angeles hospital after suffering a heart aneurysm.

The adult film actor admitted himself into Cedars-Sinai Medical Center on Tuesday (29Jan13), complaining of severe chest pains.

His condition worsened overnight and he has since been receiving treatment in the intensive care unit.

Jeremy's manager, Mike Esterman, tells Tmz.com the 59 year old is currently being prepared for emergency surgery.

The star, who has appeared in over 2,000 porn movies throughout his career, had been booked to appear at a Super Bowl Sunday party this weekend (03Feb13) in Dedham, Massachusetts, although it is not yet known if he will be well enough to honour the commitment.
