Amber Heard's love letter reveals Johnny Depp's nickname

The very public trial of two famous actors Johnny Depp and Amber Heard is expected to conclude next week, but many are wondering about nicknames mentioned in the couple’s correspondence.

Last week, jurors were shown love notes written by Heard to Depp in 2015. The notes describe the Pirates of the Caribbean star as a friend who Heard had fallen in love with.

The Aquaman actress shared her feelings for Depp in her letter as she penned: “True love isn’t just about the madness of passion or instead picking the safety of peace. No it’s about having both. Falling madly in love with your friend.”

Gushing over Depp, Heard continued: “You are the last thing in the whole world who deserves it, [the] last person I ever meant to hurt. I love you, Steve. I am so forever yours. XX Slim.”

The actor's full name is John Christopher Depp II, so the moniker ‘Steve’ is obviously nothing to do with his given name. Fittingly for a couple who met while working on a film set, the nicknames comes from the 1944 movie To Have and Have Not.

The film features Lauren Bacall and Humphrey Bogart in lead roles, and their characters are named Slim and Steve, respectively.

Just like Heard and Depp, the fictional characters have a major age disparity (Depp is 22 years her senior). However when explaining the nickname during his testimony last month, Depp outlined the origins of the two nicknames in his mind.

“I was the old craggy Bogie, and she was this beautiful creature, this stunning creature,” he told the court.

In recent days the love notes have become a key part of the trial, purportedly giving an insight into the relationship between the two actors while there were together in 2015.
