The famous and the mystery of the tattoos of stars

It is true that the famous are not very original and that long ago that tattoos are a fad among celebrities, so the vast majority have at least one. But I've noticed lately some motifs recur, especially the stars.
Look for Giselle Bundchen and Eva Longoria. Beyond that coincidentally have been photographed in a similar pose and a dress very similar, have a star tattooed the same size and shape in the same spot on his left wrist.
What is the reason? Will it be some kind of symbol related to the Kabbalistic mark of belonging to a secret society or just a coincidence of fashion?
Behind the jump to see other famous stars are also tattooed on his body.

Penelope Cruz. In addition to his ankle very well-known tattoo (number 883), Wing also has a star on his left wrist. But it is so small that, sadly, the cameras can not capture the image clearly.

Lindsay Lohan. As she does not like being out of nothing, also tattooed his little star.

Ashley Simpson. She is another that also has the star on the left wrist (this is beginning to intrigue me more and more).

Avril Lavigne. While the shape is different, its also a star tattoo on his wrist and is left!

Kate Hudson. This daring nude made for InStyle magazine uncovered that has a five-pointed star like the Giselle and Eve, but in the left foot.

Rihanna. In the absence of a star, the singer from Barbados is made at least three dozen, of all sizes. Apparently nobody told him that the wave was in the wrist, so she chose the neck and his upper back.

Sienna Miller. Jude Law's girlfriend is another to be tattooed pentagrams. But he chose to be more discreet, so only 3 and tattooed on his right shoulder.
