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, 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 weekendin Dedham, Mass., although it is not yet known if he will be well enough to honour the commitment.

Reality TV stars Heidi Montag and Spencer Pratt frittered away their $10 million fortune because they believed the world would end in 2012.

In 2010, Pratt revealed the couple was broke and on the verge of bankruptcy, and they even gave up their luxury home and moved in with his father to save money.

He has now admitted they deliberately spent all their cash before December 21, 2012 — the day the world was set to end, according to a prophesy based on the Mayan calendar.

He tells Britain’s OK! magazine, “We made and spent at least 10 million dollars. The thing is, we heard that the planet was going to end in 2012. We thought, we have got to spend this money before the asteroid hits.

“Here’s some advice, definitely do not spend your money thinking asteroids are coming. But the world didn’t end.”

Opening up about his extravagant lifestyle, Pratt adds, “I would give my friends $15,000 for their birthday. Just cash. I would buy people cars. Every valet I met got a couple of hundred pounds tip. I would pay people $200 just to open doors for us.”
