Nice girl Hilary Duff is mixing things up and guest starring on NBC’s ‘Community’ tonight as a mean girl. The busy actress who just got married to Hockey star Mike Comrie, told me recently on a conference call that she loved playing the bitchy character on the quirky and funny ‘Community’ for obvious reasons. Hilary, who has done a great job of avoiding the pitfalls of Hollywood, has also guest starred on the highly popular ‘Gossip Girl’ last year and has a new book out right now on top of the NY Times Best Seller List called ‘Elixir.’ And for those that don’t know Hilary is also a singer who has released records in the past and worked with writer/producer/ex American Idol Judge Kara DioGuardi. Plus she’s filming or just filmed or will film movie “She Wants Me” the same film real life bad boy Charlie Sheen will be in. And she’s a huge dog person and has a few. So there, now you know all about Hilary. Check out Hilary’s mean girl role tonight at 8p on NBC.
