Jagger Urinated On Warhol's Art

The jewellery designer spent a lot of time at Warhol's legendary Factory studio in New York City when she was a kid in the wake of her famous father's divorce from her mother Bianca in 1978.

And Jade nearby caused an upset during one of Warhol's babysitting sessions when she soiled one of his creations - but insists the artist wasn't angry.

She explains to German magazine Gala, "I spent a lot of time during the day at Andy's. I had my first glass of champagne with him. No wonder I peed on his photo base paper once! But he didn't freak out, he liked the effect and later asked me to do it again."
