Lady Gaga has revealed she only has tattoos on the left side of her body, as her father asked her to remain "normal" on one side.
The Born This Way singer - who has attracted attention in the past by wearing a dress made of raw meat, going out in just her underwear and wearing sculpted horns on her head - revealed in a question and answer session at Google headquarters she keeps her right side conservative in respect of her father Joseph Germanotta.
Lady Gaga said: "All of my tattoos are on one side, per my father's request. He asked that I remain, on one side, slightly normal, so I only have my tattoos on my left side.
She added: "I think that he sees the right as like my Marilyn Monroe side and the left as my Iggy Pop side."
But Lady Gaga, admits it is her wild left side of her split personality that is the most powerful.
She said: "I think, from a neurological standpoint, I'm creatively driven by my left side. But he's asked that I don't get any on the right side, for whatever reason."
The 24-year-old singer revealed she suffers to keep in shape, performing Bikram yoga in a room heated to 100 degrees.
Lady Gaga also told how The House of Gaga team who work with her on her tour often tease her about her strict diet.
She said: "There's a lot of backstage shenanigans. Very often they will make jokes about my diet because they know I have to stay fit for videos. So they'll leave mounds of cheeseburgers in my dressing room. It's really awful."
