Johnny Depp tricked Amber Heard into believing her car was stolen.
The 52-year-old actor's wife freaked out after he and her father secretly arranged for her 1968 Ford Mustang to be renovated by custom car designer Chip Foose on an upcoming episode of the reality TV series 'Overhaulin'.
In a clip from the show, which sees a team of mechanics and designers revamp old vehicles, the 29-year-old actress takes her frustration out on a man posing as a police officer, who keeps taking pictures of the famous couple, and demands: "Why is he filming?
"Get my car back!"
Another extra posing as the police officer's partner explains: "I'm sorry he gets really starstruck. We met John Claude Van Damme one time and we had to get a restraining order."
They then force the couple to take a picture with them for a "newsletter" much to Amber's annoyance.
When the 'Rum Diary' beauty finally finds out that her car is fine and has been upgraded with the help of her husband for the show, she says: "I'm overwhelmed!
"I bought it as kind of a drivable piece of junk, a beautiful piece of junk. The car cost me every dime I had and continued to cost me for the first eight years that I lived in LA. I don't let anyone touch my car. I can't believe it."
Upon seeing her new cherry red vehicle, she breaks down in tears and adds: "I'm sorry. I can't believe it! Oh my God, thank you so much!"
Asked how he managed to keep the prank a secret, Johnny admits: "Well you know there's only so many times you can change the subject."
