Where You've Seen Her: This native New Yorker garnered Hollywood's attention playing Sean Penn's daughter in 2003's Mystic River. From there her career took off, landing roles in blockbusters like The Day After Tomorrow, The Phantom of the Opera, and Beautiful Creatures. These days, we know her best as Fiona, the eldest sibling in the dysfunctional Gallagher family, on Shameless. Catch the show's fourth season premiere this Sunday on Showtime - and take pleasure in knowing that at least your family isn't half as fucked up as these folks.
