Actress Winona Ryder was taken to hospital on Wednesday after falling ill on a flight from Los Angeles to London, but her spokeswoman called it a "precautionary measure" and she was quickly discharged.

The 37-year-old star was taken to Hillingdon Hospital in west London, according to British media.

"She did fall ill on a flight and as a precautionary measure, was taken to a hospital," said a spokeswoman for Ryder. "She was there maybe an hour and was released. The bottom line is she is in good health."
