Angelina Jolie's six children are obsessed with her tattoos.

The 'Maleficent' star - who raises Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and five-year-old twins Knox and Vivienne with fiancé Brad Pitt - loves that Shiloh and Pax are especially fascinated by her 13 pieces of body art, including the etchings of their birth location coordinates.

A source told Us Weekly magazine: ''They are obsessed with her tattoos and always ask that they mean.''

The actress thinks it's amusing that Pax has already expressed an interest in getting his own inking.

But the insider said: ''Angie tells him he has plenty of time.''

Angelina and Brad - who got engaged in 2012 - are even said to be planning on commemorating their upcoming marriage with some matching inkings.

A source said earlier this year: ''[They are deciding] with what and where they will ink themselves to mark their long-awaited marriage.

''Brad really wants to do something special, and frankly, a little weird to mark the occasion, and they want to get the exact same design, in the exact same spot in their bodies.''
