This seems like the most inconsequential news in the world in light of her recent divorce announcement, but Jenna does have a major motion picture coming soon. It's called "Walk Hard" and seems to be some kind of spoof on the musician biography genre, with special care taken to satirize that Johnny Cash one. John C. Reilly plays the Cash-like character and Jenna plays his songstress paramour. Oh, and yes that is Paul Rudd as John Lennon and Jack Black as Paul McCartney. That one scene alone ought to be worth the price of admission.
The film is being produced by Judd "Superbad" Apatow and is being released just in time for Christmas, December 21st. Buy someone you love a ticket. Do it for single Jenna.
