Johnny Depp's Assistant Says Texts Were Doctored

Johnny Depp's assistant, Stephen Deuters, tells TMZ, the texts that were posted in which he allegedly apologized to Amber Heard for Johnny's violent behavior are heavily doctored ... and he never said Johnny attacked her.

Deuters says he knows of no acts of abuse toward Amber at the hands of Johnny and has never made such a claim to anyone. He adds, Johnny has never been violent toward anyone he knows.

Deuters says the texts themselves are suspicious because they don't even show a date.

Bottom line ... he says he will testify under oath he never had a conversation about alleged violence with Amber.
