Washington, October 28 : Angelina Jolie has revealed that she designed partner Brad Pitt’s tattoo of bizarre lines during a bored night in.

The actress confessed that the series of lines across the mid-section of Pitt’s back was the outcome of their bored night in while they were attending the World Economic Forum.

"One night we didn''t have anything to do, so I was drawing on his back,” Contactmusic quoted her as telling Entertainment Weekly.

"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.

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