SPOTTED: Christian Serratos, star of AMC’s hit show “The Walking Dead,” took a break from the apocalypse with a recent visit to Universal Studios Hollywood, where she took on a few “The Simpsons” themed carnival games.  The theme park will open “Springfield,” an immersive three-dimensional version of “The Simpsons’” hometown adjacent to “The Simpsons Ride,” complete with signature eateries such as Krusty Burger, Moe’s Tavern and Duff Brewery in Spring 2015.
