In her Vanity Fair profile, where she revealed some of her dirtiest secrets (Johnny Depp and drugs), 38-year-old Moss also revealed that she was tattooed by revered German painter Freud. Freud and Moss met in 2002 and shortly after, he etched swallows at the base of her spine.
"He told me about when he was in the Navy, when he was 19 or something, and he used to do all of the tattoos for the sailors. And I said, 'Oh my God, that's amazing,'" she told Vanity Fair. "And he went, 'I can do you one. What would you like? Would you like creatures of the animal kingdom?'
"I said I liked birds and he replied, I've done birds. And he pointed down at a painting of a chicken upside down in a bucket to which I replied, "No, I'm not having that." We decided to do a flock of birds," she said.
Moss also admitted she knows the tattoo could be worth a fortune, which many publications, like the (U.K.) Telegraph, have estimated to be over $1 million.
"I mean, it's an original Freud. I wonder how much a collector would pay for that? A few million? If it all goes horribly wrong I could get a skin graft and sell it! It's probably the only one on skin that's still around," she said.
Moss met Freud in 2002 after admitting he was the person she'd most like to meet. The duo linked up after Moss agreed to pose for a nude painting while pregnant with Lila Grace.
"I went to his house and he started [the nude painting] that night. Couldn't say no to Lucian. Very persuasive. I phoned Bella [his daughter] the next day and said, 'How long is it going to take?' She said: 'How big is the canvas?'. I said, 'it's quite big.' She said: 'Oh dear, could take six months to a year."
The painting ended up taking nine months to finish and went for £3.9 million during an auction in 2005.
Freud died in July 2011 at 88-years-old.
