When producers knocked on the door, we're told a young woman answered, and informed producers her mother had just suffered a stroke and she didn't know what to do.

According to sources, producers notified several on-set SF police officers -- who then rushed into the house, where the woman's mother was located. Soon after, an ambulance arrived and transported the woman to a nearby hospital for treatment.

Sources say Tila was in and out of consciousness in the house ... and officials decided she needed psychiatric help, stat.

Tila was released ... but the drama didn't end there. Last night, Tila's manager had a sneaking suspicion something was terribly wrong, so she called 911.

Taking Back Sunday singer Adam Lazzara is lucky to be alive -- after a tree literally FELL on top of him this weekend ... shattering his leg.

The rest of the band ran outside when they heard his calls for help -- but couldn't lift the tree off him ... so they called 911, and the local fire department came and sawed the tree to pieces (below).

Once freed, we're told Adam was rushed to the hospital -- where doctors put a cast on his broken leg. According to the rep, Adam's expected to be in the cast for the next 4-6 weeks.

Former super model Rachel Hunter jumped into action moments ago in L.A. -- phoning emergency personnel after a high-speed collision occurred just a few yards away from her ... and it was all caught on tape!!!

The footage is intense -- several photogs crowd around Rachel asking her typical questions ... then out of nowhere ... BAM!!! ... a small white Mazda t-bones a Suburban, sending it spinning out of control.

It's hard to see from the tape -- but the Suburban makes a blind U-turn while Rachel is crossing the street and the Mazda doesn't see it. The rest is metal-twisting glass-smashing history.

TMZ has learned ... Jung was allowed to leave the confines of the prison in December ... and was transported to a nearby facility so doctors could remove a suspicious mole on his nose.

One source tells us Jung believes the mole is a direct result of the long hours he spent lingering in the Mexican sun -- hobnobbing and negotiating with the country’s top drug lords.

Prison officials are refusing to comment on Jung’s current health status, but our sources say the surgery was a success ... even though Jung remained shackled during the entire hospital procedure.
