dinner hollywood John Mayer hat musician singer scarf katsuya

Apparently this look is no shtick - John Mayer is channeling Johnny Depp for the long haul.

The singer sported a denim jacket, feather pendant, cobalt scarf, gray jeans and yet another Indiana Jones-like brimmed hat - to dinner with friends at Katsuya in Hollywood Thursday night.

Maybe the boho look is inspiring his next album ... Jack Sparrow is a wonderland?!
