We're a long way from the time when you had to get a tattoo in secret! In Los Angeles, tattooists are stars in their own rights, and Mark Mahoney is one of the most well known. Specialising in black-and-white styles, he tattoos in his studio, the Shamrock Social Club. His technique, which only requires one needle, gives amazing results and has already attracted stars like Brad Pitt, Johnny Depp, Lady Gaga and Johnny Hallyday. If Mahoney is to be believed, he has even tattooed a former President of the French Republic... And what's more surprising, this tattoo king has recently launched a line of clothing... for children!
