The 'Mortdecai' star made a surprise appearance at the 'Beautiful People' singer's concert at The Tivoli in Brisbane, Australia on Friday (27.02.15) night.

Introducing his friend, Marilyn said: "If you don't recognise my personal friend... my personal saviour, my personal guitar hero... Johnny Depp."

The 51-year-old actor - who recently tied the knot with Amber Heard - is currently in Australia filming the fifth instalment of the 'Pirates of the Caribbean' series, 'Dead Men Tell No Tales'.

Meanwhile, it was recently announced that Johnny would be forming a supergroup with Alice Cooper and Joe Perry.

A message on the 'Poison' hitmaker's website read: "Alice Cooper and Johnny Depp have been partners for a while and now with Joe Perry also on Hollywood Vampires, they will 'rock it out' yet once again."

The Hollywood hunk, though, has previously admitted he finds it embarrassing when actors move into the music industry.

He said: "I've been very lucky to play on friends' records and it's still going. Music is still part of my life, but you won't be hearing The Johnny Depp Band. That won't ever exist.

"I hate the idea, 'Come see me play the guitar because you've seen me in 12 movies'."
