Age is important enough to Jennifer Herrema that she feels the need to lie about own. 
Here is a brief list of people younger than her: Billy Corgan Liz Phair, Kylie Minogue, Marilyn Manson, Dave Grohl, Elliott Smith, Cat Power, Jack White, and Alison Mosshart.
On the plus side, you may now a historically claim these…

sorry Janelle, but in the real world Jennifer is OLDER than both those people. She lies about her age ('67 not '72) and has been called out for it several times before by those in the know.  But as you are not a real fan it stands to reason you would not be aware of this.
