Troubled singer Amy Winehouse was treated and released from a London Hospital today (Jul 29) after being rushed to the emergency room yesterday for what her spokesman said was an adverse reaction to medication. Winehouse’s spokesman Chris Goodman said the R&B/Pop singer was discharged from London’s University College after spending the night in observation, but he did not state if the prescribed meds were the real cause of her visit. “She had a bit of a scare yesterday because of a reaction to treatment. She was kept in overnight purely for observation,” Goodman said in a statement. “Amy is at home now after leaving with her father and manager. She is having a rest.”
