Amber Heard suddenly dropped Kate Moss’ name into Johnny Depp’s bombshell defamation trial Thursday, as she alleged the actor once pushed the British supermodel down the stairs.

Heard, 36, made the claim during day two of her testimony in Fairfax, Virginia as she detailed a slew of alleged violent fights she had with Depp over the course of their soured romance.

The “Aquaman” actress briefly mentioned Moss while describing the time she punched Depp in the face for the first time out of fear he was going to shove her sister Whitney down a staircase.

Heard said she and her then-husband had been fighting on the mezzanine of the stairs in one his many penthouses in March 2015 when her sister got in between them.

“She threw herself in the line of fire,” Heard said of her sister. “She was trying to get Johnny to stop. Her back was to the staircase, and Johnny swings at her.

“I don’t hesitate and wait — I instantly think of Kate Moss and stairs.”

Moss and Depp dated between 1994 and 1998.

Heard first dropped the Moss staircase bombshell allegation when she testified during Depp’s other defamation trial in the UK in 2020.

Describing the same fight involving her sister, Heard told the British court at the time: “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 rumor from two people and it was fresh in my mind.”

In that trial, Depp’s lawyers accused Heard of fabricating the Moss “rumor” and dropping into her testimony at the last minute out of spite.

The lawyer said Heard had never previously mentioned the claim, including in her deposition and witness statements ahead of that trial.

Moss hasn’t ever publicly addressed Heard’s claim Depp pushed her down the stairs.

Heard is currently defending herself in Virginia against claims she defamed Depp when she wrote a 2018 op-ed in the Washington Post describing herself as “a public figure representing domestic abuse.”
