Kate Moss to testify in Johnny Depp-Amber Heard trial after Heard brought up staircase incident

Johnny Depp’s ex-girlfriend and supermodel Kate Moss is all set to testify in his and Amber Heard’s defamation trial, currently underway in Virgina, US.

Why: On May 8, Amber Heard testified that the first time she punched Depp was because she thought that he was going to push her sister Whitney down the stairs. Heard testified, 'She [Whitney] threw herself in the line of fire. She was trying to get Johnny to stop [fighting with Amber]. Whitney's back was to the staircase, and Johnny swings at her ... I don’t hesitate and wait, I instantly think of Kate Moss and stairs.'

Heard had previously testified, while describing the same fight involving Johnny, Amber and Whitney, 'I remembered information I had heard (that) he pushed a former girlfriend - I believe it was Kate Moss - down the stairs. I had heard this rumour from two people and it was fresh in my mind.'

By mentioning Moss in her testimony, Heard gave the Depp team the opportunity to call on Moss as a witness and testify in the ongoing trial.

Why did Heard bring up Moss? Kate Moss and Johnny Depp dated from 1994 to 1997. During this time, in September 1994, Depp and Moss got into a fight at New York's Mark Hotel, when Moss accused him of cheating on her.

The NYC Police arrived at the scene and Depp was arrested for trashing his hotel room. He was charged with 'criminal mischief' and asked to stay out of trouble for 6 months by a criminal court judge. Depp paid around US $10,000 in damages, and the charges were dropped. (Read more here: Johnny Depp and Amber Heard trial: What is the Kate Moss staircase incident)

Although the Robb Report reported that Moss was found 'dishevelled' at the scene by the NYPD, People reported that the NYPD found Depp in a state of 'possible intoxication' and Moss 'uninjured'. This incident led to rumours that Depp had pushed Moss down a flight of stairs.

Neither Depp nor Moss have ever commented on the rumours, and Kate’s testimony now will be the first time the incident will be talked about.

Moss will be testifying on May 25 and lawyers from both sides will be making closing statements on May 27.
