64. Maggie Gyllenhaal & Peter Sarsgaard
Maggie and Peter saw a nice jump up on our list this year, thanks to their proven longevity: They've been dating since 2002 and finally tied the knot last spring. Maggie also had a big year in her career, having been nominated for an Oscar for her role in Crazy Heart. She didn't win, but they both have films coming out in 2010, so their work and home lives seem to be on the up-and-up.
