The 22-year-old socialite, who is the daughter of musician Sir Bob Geldof, says that she wishes her father had stopped her getting at least some of her 20 tattoos because she was too young to make sensible decisions.
Peaches told The Sun: "14-year-old girls should not be allowed to have tattoos. The ones I have from that age are like prison tattoos. I recently came to the conclusion [that] I regret every one I've had. I have so many bad tattoos. Some I find horrendous. If I could graft myself a new skin, I would."
In 2009, the star's ink work was photographed on the beach in Mexico for the first time. The designs included the name of her ex-husband Max Drummey, rosary beads, a broken heart, a playing card and a snake symbol.
She admitted a year previously that tattoos were her "new addiction", while a friend said: "Peaches has caught the tattoo bug and loves symbolising important landmarks in her life."
She then said: "It's obvious I'm not dressing for men. I don't want to be sexy, I'm, like, covered in tattoos. I have piercings. I'm just grungy and weird and not what is socially accepted as being beautiful, and I think that's cool. I don't want to dress for men, I think it's almost like a feminist thing."
Peaches recently hit back at reports that she has been "flaunting" her slim figure after losing weight this year. She said that she only posts pictures of herself online because she wants advice on what clothes to buy and insisted that she "eats like a horse".
