Jennifer Garner has a new alias: Mommy-to-be. According to E!, the Alias badass and boyfriend Ben Affleck are expecting their first child. The news comes just weeks after the couple reportedly got engaged. It's not clear what impact this will have on Garner's Alias duties, but if rumors of an October/November due date are true, the actress could be sidelined through January. Sounds like a good time for J.J. Abrams to introduce Syd's long-lost sister, Felicity Bristow.
