Happy: Johnny Depp was all smiles as he arrived for his band's gig at Coney Island in New York on Sunday night

Johnny plays guitar and sings back-up for the band Hollywood Vampires and several of his adoring followers could not pass up the opportunity to see the talented star.

He did not leave them disappointing as he smiled from ear-to-ear while waving and even clapping for his fans while heading into The Amphitheater in Brooklyn.

The Pirates Of The Carribean star donned his regular rocker chic look as he sported a worn-out black T-Shirt with baggy blue jeans featuring paint spots and fades on it.

He also wore black leather lace-up boots as he tied a camouflage jacket around his waist along with a scarf draped out of his denim pocket.

Round of applause: He even clapped for fans in attendance

Rocker chic: He wore a beat-up old black shirt, baggy jeans, lace-up boots, aviator shades, necklaces and had a camouflage Army jacket tied around his waist

Johnny accessorised with white-rimmed aviator shades,many necklaces and a scarf wrapped around his neck and several bracelets with a watch.

His short tapered locks were done in a pompadour as he sported just a bit of scruff in the mustache and chin area. 

The aviator shades, Army jacket and even haircut were definitely reminiscent of Robert De Niro's character Travis Bickle in 1976 classic film Taxi Driver.

The gig did have a scary moment, however, as Depp's bandmate and legendary guitarist Joe Perry fell ill and had to leave the stage.

The 65-year-old Aerosmith member sat down and struggled to play before he had to be treated by medics backstage during the Hollywood Vampires's first song.

He was taken to the hospital in critical condition, but has since stabilized according to several reports.

The gig comes just days after reports that he has turned to self-expression to help him cope with the unpleasantness of it all, reportedly altering a tattoo on his right hand to read 'Scum'.

According to TMZ, the actor inked his knuckles with the word SLIM - Amber's nickname - shortly after they married last year, but, as a series of photos show, he has now tweaked the inking to spell SCUM.

The Pirates Of The Caribbean actor was recording a video message for 95.5 KLOS with a microphone in his right hand when eagle-eyed fans spotted a change in his knuckle dedication.

Johnny has plenty of experience using body art to cope with relationship woes.

During his four-year partnership with actress Winona Ryder in the early 90s, Johnny tattooed the phrase Winona Forever on his upper right arm.

Following their highly publicised split he altered it to read 'Wino Forever.'

Johnny and Amber did not have a prenuptial agreement which entitles her to half the money he made over the course of their relationship, which looks to be somewhere between $20 and $30million.

Heard, 30, had also asked a judge for spousal support and her legal fees to be covered during the divorce, but that was rejected by the court.

Luckily for Johnny - who is worth an estimated $400million - he made a good chunk of that possible payoff this week by selling two of his prized Jean-Michel Basquiat paintings for $11.5 million.

A 1981 three-paneled piece titled Self Portrait was expected to land $1.9 million. It was snapped up by New York gallery owner Bill Acquavella for $4.7 million.

The second, another 1981 piece painted on the back of a door titled Pork, had an estimated price tag of $3-5 million. It sold to an anonymous phone bidder for $6.8 million.

Depp spent 25 years collecting eight of the Brooklyn artist's groundbreaking pieces, and now intends selling the other six.
