LONDON – Amber Heard alleged in a British court on Wednesday that her ex-husband Johnny Depp threw "30 or so bottles" at her as if they were “grenades or bombs” while they were in Australia in March 2015 and that he accidentally severed part of his finger during the assault.Taking to the witness box for a third day at the High Court in London during Depp's libel case against a British tabloid, the actress refuted his allegation that it was she who lost her temper and that she had injured him.Heard has described her stay in Australia with Depp as akin to a “three-day hostage situation." The incident is central to The Sun’s labeling of Depp in an April 2018 article as a “wife beater.”Depp, 57, is suing The Sun’s publisher, News Group.
