07. Isabella and Isotta Ingrid Rossellini



 The daughters of silver screen icon Ingrid Bergman and legendary Italian director Robert Rossellini, fraternal twins Isabella and Isotta Ingrid Bergman took very different paths. Isabella used her flawless beauty to launch a modeling career, act in such films as "Blue Velvet" and "Fearless," and land famous lovers, like Martin Scorsese (her husband from 1979 to 1982), David Lynch, and Gary Oldman. Ingrid, on the other hand, chose to stay out of the spotlight. After earning a PhD in Italian Literature at Columbia University, Ingrid became a professor and has taught at Harvard and Princeton. And, proving that twins don't always think alike, the sisters had a very public rift in 2006 when Isabella screened her short film "My Dad Is 100 Years Old" prior to a retrospective of his work at the Tribeca Film Festival. Ingrid felt the short made a joke of her father's illustrious career and was hurt that Isabella would link it directly to his film during the festival.

09. Alanis and Wade Morissette



Isn't it ironic that Alanis Morissette has a twin? No, not really, but neither were any of the things that Morissette talked about in her 1996 hit song "Ironic." But we digress. Wade played piano and guitar growing up, but it wasn't until he combined his passion for yoga with his love of music that he found his true calling. As a spokesman for lululemon athletica apparel, Wade joined the Yoga Pilgrimage in 2005 and toured to promote his debut album, "Sargam Scales of Music." He's been rocking the yoga circuit ever since. Maybe if Wade had taught Alanis how to align her chakras, "Jagged Little Pill" might have been a kinder, gentler album.
