Los Angeles, California - Actor Anne Heche has reportedly passed away.

The actor had been in a coma with severe injuries at the Grossman Burn Center at West Hills Hospital north of LA following a horrific car accident on August 5 where she crashed into a residential house, setting it on fire.

One day before her passing, a rep for Heche's family said the 53-year-old had a severe anoxic brain injury and was not expected to live. The rep also noted that she was being kept on life support to assess whether any of her organs were viable to be donated, as doing so had "long been her choice."

Ellen DeGeneres, who dated Heche from 1997-2000, commented on the tragic news of her passing via Twitter: "This is a sad day. I'm sending Anne's children, family and friends all of my love."
