Former reality star Tila Tequila has some serious head problems. The troubled sex siren suffered from a brain aneurysm that nearly killed her, according to RadarOnline.com. The petite tabloid staple was supposedly on the brink of death last week, an insider reveals. The source tells Radar, "It was terrifying for Tila, and death was knocking at her door. She was in two hospitals for the span of a week and is still not in perfect health, so she's going to check into an outpatient program." The 4'11" star went from a healthy 100 pounds to a sickly 78 pounds. The source says that the 30-year-old woman had a brain aneurysm in the middle of the night that caused her to become disoriented. She then downed not one, but TWO, bottles of heavy prescription meds. The insider recounts the frightening incident that left the one-time Internet sensation fighting for her life: "Tila threw up all over her bed after overdosing and felt like she was dying. She was screaming for help, and in desperation, broke her bedroom window and attempted to jump out. Finally a friend came over after getting a strange text from her and found her convulsing on the bed. He called an ambulance and she was taken to the hospital." Based on her bizarre past, it may sound like just another night for the recovering addict. But the source maintains this time it was far more serious. Tequila was rushed to the hospital where she spent a week in intensive care. So far, it's difficult to say whether the brunette beauty will make a full recovery. The source adds, "It's sad to think she may have some permanent brain damage. She still can't fully speak properly."
