So we all know about Mary-Kate and Ashley Olsen, and any parent of tweens has also heard a good bit about Dylan and Cole Sprouse. But I sure didn’t know about some of these other celebrity twins. Did you?

• Keifer Sutherland and his sister, Rachel
• Scarlett Johansson and her brother, Hunter
• Ashton Kutcher and his brother, Michael
• Gisele Bündchen and her sister, Patricia
• Giovanni Rabisi and his sister, Marissa
• Jon Heder and his identical brother, Daniel
• Isabella Rossallini and her sister, Isotta Ingrid
• Jill Hennessy and her sister, Jacqueline
• Alanis Morissette and her brother, Wade (pretty ironic, don’t you think?)

Fascinating stuff. And you heard it here!
