Johnny Depp doesn't want the hassle of memorizing his lines. According to his former managers at The Management Group, the actor hires a full-time sound engineer to feed him his lines on the set. He reportedly spent "hundreds of thousands of dollars" to keep the engineer on yearly retainer.

The revelation came amid Deep's legal battle against his former managers at TMG. The "Black Mass" actor sued them for alleged fraud, but the managers respond by claiming that the star has no one but himself to blame. They slam him for having a "clear and epic" sense of entitlement.

"Depp listened to no one, including TMG and his other advisors, and he demanded they fund a lifestyle that was extravagant and extreme," the managers' attorney says. "Ultimately, Depp and/or his sister and personal manager, Elisa Christie Dembrowski, knowingly approved all of Depp's expenditures."

TMG points to Deep's recent interview with The Wall Street Journal in which he said, "It's my money. If I want to buy 15,000 cotton balls a day, it's my thing." His excessive spending included the purchase of 14 residences, 45 luxury vehicles, 70 collectible guitars, 200 works by famed artist, and tons of Hollywood memorabilia.

The managers also open up that a huge amount of Depp's money was spent on bailing him out of legal crises. The details of the hush-hush money will be revealed during the trial, they say.
