pretty cool. i did a google search and found that it's a genetic condition. Also seen a base ball player with the same condition.
This condition is natural and happens to many people. A famous Bollywood actor "Hrithik Roshan" also have two thumbs.. Can be seen in this pic.
I'm sure that everyone would knock her back saying, 'Oh dear, you have polydactylism so we can't date' - yeah, right.
I dont get how people can say she has no thumb, you can clearly see it, and no its not her shoulder (if it is, then she would have a deformed shoulder as well). Shes not really hot, and I wouldnt have noticed the 6 fingers if it didnt point it out
