Amber's Ambush: Caught on Tape!

Admits she smashed Johnny Depp’s head by slamming door!

DURING one of their frequent marital blowups, raging Aquaman babe Amber Heard smashed Johnny Depp so hard with a door, she knocked him to the ground!

The bombshell revelation comes from therapy tapes, where the now-divorced but still battling pair thrashed out their issues and Amber admits to battering the Pirates of the Caribbean star.

On the audio, the 33-year-old bisexual blonde admits knocking her 56-year-old hubby to the floor by slamming a bathroom door in his face and then socking him in the jaw.

Depp notes: “I then stood up, I don’t even know if I said — I mean, I might’ve said like, ‘What the f**k,’ you know, whatever. ’Cause I’d just been hit in the head with a f**king corner of the door.
