Johnny Depp and Amber Heard arrive in court

Actor Johnny Depp returned to the stand Wednesday for testimony in his libel lawsuit against his ex-wife Amber Heard.The "Pirates of the Caribbean" actor has accused Heard of indirectly defaming him in a 2018 opinion piece that she wrote for The Washington Post.

Heard refers to herself in the article as a "public figure representing domestic abuse." The piece doesn't name Depp, but his attorneys argue that it clearly references a restraining order that Heard sought in May 2016, right after Depp told her he wanted a divorce. Depp denies abusing Heard, but Heard's lawyers say evidence will prove that he did. The actor's denials, they argue, lack credibility because he frequently drank and used drugs to the point of blacking out and failing to remember anything he did.
