Johnny Depp has gone from calling Amber Heard the love of his life to the scum of the earth ... all with a simple tattoo alteration.
Depp inked his arm in Amber last year, shortly after they married. He inked the knuckles on his right hand, "SLIM" ... her nickname.
In the last week or so, he changed the L to a C and the I to a U ... and you don't need to watch "Wheel of Fortune" to know it now spells SCUM.
It's not the first time Johnny's tattoos turned ugly. Back in the day, when he was dating Winona Ryder, he had a tat that read, "WinonaForever." When that relationship fizzled, he changed it to "WinoForever."
