There are, of course, many famous twins in the world. Mary Kate and Ashley Olsen, for example. TV stars Cole and Dylan Sprouse  and Tia and Tamera Mowery are a couple more. But there are a number of big, big stars who have a twin...whose names you've never heard.

Start with super model Gisele Bundchen and her older (by five minutes) sister Patricia. Then there's 'A list' actress Scarlett Johannson. Who knew she had a twin (brother Hunter, in the photo below)? Or how about '24' star Keifer Sutherland? Well, back home in Canada he has a twin sister, Rachel. And didja know about Ashton Kutcher's twin brother Michael?

Other stars with a twin include Jon Heder (Napoleon Dynamite), actress Isabella Rossellini, singer / songwriter Alanis Morissette, singer Aaron Carter and action star Vin Deisel.

And finally, the twin of one show business' greatest legends, Jesse Presley, brother of Elvis. Sadly, little Jesse, 35 minutes older than his famous sibling, died shortly after birth.
