Double or Twin in This Is It or Double AND Twin??

There have been many different and loud rumors about the "This is it", many claim to know there is a double, there is not a double and so on. Here are some pictures to look at and you tell, is this the same person??

In the pictures below we have 2 diferent pictures from the same angle. Looking at eyes, lips and neck. Is that the same person? To me it looks like the one to the left have a slimmer neck and the lips are thinner. 

More eyes neck and nose

In the pictures here we see mouth, nose, ear and neck. Are the ears the same??? And the lips?? What about the nose??

Here we have the same pictures but changed position and together. Is that the same person?

The pictures below looks at first sight like the same person, but looking closer there is a difference. The clothes appears to be the same. But again the neck. The one to the left appears to have a slimmer neck. The lips are differenent. Is the chest different also?!?!

This is a picture that have been on twitter lately: 

Not looking at the name only at Michael Jackson. It is two different Michael Jackson. Again nose, eyes and lips! There is also a difference in height. 

So again, is this one person two or is it three?? 

If it's more than one who is/are the other/others?? 

Male or female?? 

Things are not what they first seems to be. A wig, make up and some practice can make miracles and the illusion is complete.

To be continued......
