American singer Demi Lovato's mother, Dianna de la Garza, has finally broken her silence over her daughter's drug overdose and said she shakes a little bit remembering what happened that day.

Garza said that she was in shock and did not know what to say. She had to break the news to Demi's sisters, Dallas and Madison. Garza said that while she knew she had to get to Cedars-Sinai Hospital, she was not in a state to drive, so Dallas offered to drive her. They jumped out of the car and ran into the emergency room to be by her side.
