Harry Styles has got a new tattoo of a skull sporting a bowler hat.

The One Direction heartthrob showed off yet another new inking during the Australian leg of the band's 'Take Me Home' world tour, sending fans into a frenzy as they shared pictures of the new artwork on Twitter.

One eagle-eyed fan noticed the new tattoo while enjoying a concert and wrote: ''everyone stop what u're doing harry styles has a new sleeve tattoo. (sic)''

The 19-year-old star's inking - which features a skull in a hat with a red rim - is located on his upper left arm, adjacent to his earlier tattoo of a ship and just above his tattoo of two hands shaking.

In September, Harry added yet another inking to his left arm - a rose - and his regular tattoo artist, Los Angeles-based Freddy Negrete, recently revealed he was devastated that the star didn't come to him to have it done.

He said: ''Harry said he would be back. I did his first tattoo and a lot of them since, until the big one when he was here with [ex girlfriend] Taylor Swift last year. I don't know why he's gone somewhere else now.

''I didn't do the rose. He didn't even get it here at the parlour. I don't know who did it.''
