Jennifer Lopez was rushed to the hospital after finding blood in her urine. Jello just finished her tour with her husband, Marc Anthony after announcing she was pregnant. A source says that the hospital visit scared the crap out of her.

"She was worried that something bad could happen. She's petrified that something could go wrong with her pregnancy."

"The hospital visit really shook her up. If she lost the baby, her life would be shattered."

Jello better watch herself. She's not a spring chicken, like the other preggo chicks around Hollywood. My mom says she saw a report yesterday which said that after her Dr. told her she needed to slow down, she fired him. I'm trying to find a source but she can't remember so I'll chalk it up to hearsay.
