Jennifer Garner

With that sweet personality and light-up-a-room smile, it's hard not to love Jennifer Garner. The 39-year-old actress landed her first leading role playing a butt-kicking CIA agent on the hit TV series Alias before appearing in flicks like Dare Devil, where she met her future hubby, Ben Affleck. Later, she showed us her funny side in 13 Going on 30, but now it seems that Jen's most important role is being a mommy. She and Ben have two daughters together, Violet and Seraphina and now the happy family is getting ready to welcome baby No. 3.
