Famous twins (or half of)

When I was younger I always wanted to have a twin sister. I guess it’s the influence of having read too much Sweet Valley Twins/High (I grew up with Elizabeth and Jessica Wakefield). It’s quite interesting to note the twin (or half of twin) celebrities out there. Among them are:

Mary Kate Olsen and Ashley Olsen
Alanis Morissette (has an older twin brother, Wade – older by about 12 minutes)
Aaron Carter (has an older twin sister, Angel Charissma – older by about 2 minutes)
Jeremy London and Jason London
Joel Madden and Benji Madden
Scarlett Johansson (has a twin brother, Hunter)
Vin Diesel (has a twin brother, Paul)
Joseph Fiennes (has a twin brother, Jacob)
Ashton Kutcher (has an older twin brother, Michael)
Isabella Rossellini (has a twin sister, Ingrid)
Kiefer Sutherland (has a twin sister, Rachel)
Gisele Bundchen (has a younger twin sister, Patricia – younger by about 5 minutes)
Linda Hamilton and Leslie Hamilton
Jessica Origliasso and Lisa Origliasso (The Veronicas)
Kofi Annan (has a twin sister, Efua)
Brittany Daniel and Cynthia Daniel (Sweet Valley Twins!)
Giovanni Ribisi (has a twin sister, Marissa)
Parker Posey (has a twin brother, Christopher)
