A tattoo artist to the stars — whose dad was bandleader Artie Shaw — pleaded not guilty to weapons charges yesterday after a cache of firearms, knives and ammo was found in his storage unit.

Jonathan Shaw, 57, whose celebrity clients include Johnny Depp and Kate Moss, was charged in an 89-count indictment with possessing a loaded AK-47, a 12-gauge shotgun, a loaded .30-caliber semiautomatic rifle, nearly 3,000 rounds of ammo and 83 knives.

Shaw was busted in November after movers hired to collect his belongings from a storage unit on South Street spotted the weapons and alerted authorities.

Shaw has claimed through a lawyer that he is a collector who bought the weapons legally 15 or more years ago.
