Johnny Depp's ex Kate Moss on why she testified on his behalf in trial against Amber Heard: 'I had to say the truth'

Model Kate Moss, who had dated actor Johnny Depp in the 1990s, has revealed why she supported him during his recent defamation trial.

In a new interview, Kate also spoke about previously supporting her friend, fashion designer John Galliano, who was found guilty of anti-Semitic abuse in 2011.

Johnny's attorneys had called Kate as a rebuttal witness after Amber had testified about a time she feared her ex-husband would push her sister down a staircase.

Amber had said she recalled "rumours" of Johnny pushing Kate down a flight of stairs and she slapped him to stop him from harming her sister.

“I believe in the truth, and I believe in fairness and justice. I know that John Galliano is not a bad person – he had an alcohol problem and people turn."

Kate, who dated Johnny from 1994 to 1998, testified that she slipped on a staircase and injured her back during a vacation the couple took in Jamaica.
