Wednesday brought a new development in the Johnny Depp vs. Amber Heard trial with another major celebrity offering testimony. Kate Moss, who had a years-long relationship with Depp in the 1990s, appeared via video link to shed some light on certain allegations made earlier in the trial. Her testimony was fairly brief as Depp's lawyer Benjamin Chew was pretty straightforward with his questioning.

At one point during the trial, Heard had admitted to striking Depp at the top of a staircase. She claimed this was in self-defense as she was afraid Depp would try throwing Heard's sister down the stairs. Heard claimed that she had heard a rumor that Depp had previously thrown Moss down a staircase, and with that in her mind, she intervened strictly to protect her sister.

Moss was directly asked by Chew about the time she visited Jamaica with Depp when the alleged staircase incident occurred. For her part, Moss told a very different story about that trip, describing Depp as her protector who was quick to offer assistance when she had a fall. As Moss explained:

"We were leaving the room, and Johnny left the room before I did. And there had been a rainstorm, and as I left the room, I slid down the stairs and I hurt my back. I screamed because I didn't know what happened to me and I was in pain, and he came running back to help me, and carried me to my room and got me medical attention."

When asked specifically if Depp had ever, at any point in their relationship, pushed her down the stairs, Moss retorted:

"No. He never pushed me, or kicked me, or threw me down any stairs."

Chew then established that Moss had never previously testified in any court proceedings. The attorney asked Moss to state why she chose to get involved in this trial, but Heard's lawyers objected before she could respond. Moss was then dismissed from the trial as Heard's attorneys declined a cross-examination.

What Does This Mean for the Trial?

Amber Heard supporters do not believe this spells doom for her case. Their argument is that even if Depp hadn't been violent with Moss, it doesn't disprove that he had abused Heard. A source close to Heard contacted MovieWeb with a statement shortly after Moss' testimony and alleged that having Moss testify was a diversion tactic employed by Depp's legal team. The statement reads:

"So Johnny Depp didn't abuse Kate Moss. That makes him 1 for 2 in the abuse column. But, to date, he’s 0 for 1 in the courtroom on the central issue in this case back when he lost the same exact case in England. And when the jury deliberates over the singular issue in this case -- whether Amber Heard can exercise her right of Freedom of Speech --- he'll be 0 for 2, no matter how much his lawyers try to distract and divert the jury’s attention."

The legal battle continues but is expected to be wrapped up on Friday.
