Harry Styles

Harry Styles' mother Anne Cox has tried to nix any new tattoos for her pop star son.

Styles' mom says she is worried his tattoo obsession is getting ''out of hand''.

Cox has pleaded with her 18-year-old son to stop getting inked so often, and she has started by successfully convincing him not to get a tattoo of his name in Japanese calligraphy during One Direction's latest jaunt in the country.

A source said: ''Harry's mum is worried his tattoo collection is getting out of hand.

''She thinks he's getting addicted to sitting in the artist's chair.

''She's concerned about the lasting effects of the scribbles all over his body and thinks he could live to regret some of them.

''Harry loves the Japanese symbols. He's determined to have Japanese calligraphy on him.

''It wouldn't surprise me if he gets it done sneakily.''

The 'Kiss You' hitmakers' mentor Simon Cowell has also urged the pop star to give his tattoo habit a rest after he got inked more than 30 times in the last 12 months.

The source added to the Daily Star newspaper: ''Simon gave him some gentle advice suggesting he gives it a break for a while and reassess.

''Harry has had over 30 tattoos in the last year. His mum is also concerned the ink could be the reason he gets such bad skin.

''She's told him he'll get even more spotty if he continues, not just on his face.''
