Today's talk you might've missed:

• An entertainment property can live and die by its title, and Peter Jackson isn't taking that risk with the final "Hobbit" film. Instead of "The Hobbit: There and Back Again," the movie's going to be called "The Hobbit: The Battle of the Five Armies." [Peter Jackson's Facebook]
• "Nashville" actress Aubrey Peeples is your new totally outrageous Jem. In her first feature film role, Peeples will portray the lead character in Jon Chu's live-action "Jem and the Holograms" movie. [THR]
• Avril Lavigne's reaction to accusations that her new "Hello Kitty" music video is racist? "LOLOLOL!!!" [Facebook]
• The "Sisterhood of the Traveling Pants" is set to ride once again. A new movie is being developed based on the latest addition to the young adult book series. [EW]
• Diane Keaton's reason for never getting married might surprise you: The actress says she wasn't "practical" enough. "I had some insane idea that I had to be 'in love,'" she says. "Now I see what it really takes: real consideration that you're a good team together." [People]
• How would you feel if Katy Perry crashed your birthday party in disguise? Yeah, we're surprised the singer made it out of these pranks for her "Birthday" music video uninjured too:
