Crucial life question: why isn’t Lizzy Caplan more famous? There are sooooo many reasons to love her, starting with Janis Ian, of course. I am not necessarily a fan of this pirate wench-y outfit she wore to the premiere of “The Campaign,” but I do strongly agree with the fantastic bob she’s rocking. I can’t wait to see her in “Bachelorette,” which premiered at Sundance, with Kirsten Dunst and Isla Fisher — I have very high hopes. Oh, and did you know that Lizzy has been dating Matthew Perry since 2006?! I did not. You learn something new (and vital) every day.
