Did Johnny Depp Change His 'Slim' Amber Heard Hand Tattoo to 'Scum?' See the Pics

While Johnny Depp has been out promoting his band Hollywood Vampires, fans couldn't help but notice something different about his tattoos.

The 53-year-old star looks to have changed the tattoo across his fingers on his right hand from 'slim' to 'scum'.

It's believed 'Slim' was in reference to estranged wife Amber Heard. The pair are currently embroiled in a contentious divorce battle.

Depp also appears to have blackened out the tattoo he had of Heard on his right bicep.

Requests for comment from Depp's rep were not returned on Saturday.

Heard, 30, filed a domestic violence restraining order against Depp in May and has accused him of allegedly abusing her.

In a response to Heard's allegations, Depp's lawyers claimed in court documents that the actress was "attempting to secure a premature financial resolution by alleging abuse.

After rocking out in Bethlehem, Pennsylvania Friday night, he will continue his holiday weekend playing more shows with the band, which also includes Alice Cooper and Aerosmith guitarist Joe Perry, up the east coast.

Earlier this week Depp enjoyed dinner with his two children – daughter Lily-Rose, 17, and son Jack, 14 – and a source tells PEOPLE he "looked very good" and "much healthier."
