Jennifer Garner

After taking a hiatus during her pregnancy with baby number two, Jennifer Garner is back on the red carpet, promoting her new movie Ghosts of Girlfriends Past. She stars as Matthew McConaughey's "one that got away" in the romantic comedy, hitting theatres this week. Jen lives out her own real life romance with husband Ben Affleck and two beautiful little girls. It looks like motherhood hasn't changed her famously toned physique and perfect posture.
