Pop singer Ashlee Simpson was horrified when she collapsed in Japan right after a concert, because when she woke up, she was in an emergency room with blood splattered all over the walls, according to a published report.

The singer was promoting her new album, ‘Autobiography,’ and her very bury schedule was too much to bear.

She said, “I finished my US tour and went straight to Japan.”

She explains, “I didn’t go to a nice emergency room - I ended up in one with blood on the walls. Nasty.”

“I was dehydrated. I had bronchitis.”

She adds, “Who knows exactly what it was? I think it was just complete exhaustion.”
