Did they change the JPG bottles or did i get a fake?

i bought a bottle of Jean Paul Gaultier Le Beau Le Parfum from Ediscountperfumes.com and i opened it and smelt it and it smells nothing like the one i had before i had both bottles on hand the sizes are different and they smell different i dont know if its because it was in the box or should i let it sit im confused and a little frustrated
