Kate Moss to Testify in Johnny Depp and Amber Heard Trial

Kate Moss is getting ready to take the stand. The 48-year-old model will testify via video link on Wednesday for

Johnny Depp's team amid the actor's ongoing defamation trial against his ex-wife, Amber Heard, ET has learned.

The news comes after Heard mentioned Moss' name during her court testimony earlier this month. 

The model, who dated Depp for four years in the '90s, came up when Heard was describing an alleged 2015 altercation between her sister, Whitney Henriquez, and the actor.

"Johnny swings at [Henriquez]. I just see my little sister with her back to the staircase and Johnny swings at her and I don't even wait...

I just in my head instantly think of Kate Moss and the stairs and I swung at him," Heard claimed. "In all of my relationship to date with Johnny, I hadn't landed a blow. 

I, for the first time, hit him -- like, actually hit him -- square in the face."
