Jolie, who shares her partner's fondness for tattoos, admits the horizontal lines across the mid-section of his back were just something she did during a boring night while they were attending the World Economic Forum, reports contactmusic.com.

"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, she said.

"It's meaningful in that it has us making angles and shapes out of each other's body, that kind of a thing,� she added.
