Angelina Jolie has shattered the myth surrounding partner Brad Pitt's new tattoo - it's a scribble she created.

Experts suggested the series of lines on the actor's back represented the levees in the couple's adopted New Orleans, Louisiana, but Jolie insists the skin art means nothing at all.

She tells Entertainment Weekly magazine, "We went to Davos... (and) one night we didn't have anything to do, so I was drawing on his back.

"He just liked it! The picture everybody saw was kind of awkward, but it just lines up beautifully on his back, just enhances the part of the body I like."

"I mean, it's meaningful in that it's us making angles and shapes out of each other's body, that kind of a thing."
