George Clooney and Ryan Gosling were back together on the Cincinnati set of The Ides of March yesterday. The two actors have been working hard on the project for the last few weeks, but they've had enough free time to explore their temporary home city. Ryan especially has been seeing the sights with his visit to the local zoo with costar Evan Rachel Wood. It was another actress who kept him company on a visit to the aquarium, though — his day date with Olivia Wilde has fans wondering whether or not they're Hollywood's hottest new couple. George apparently isn't wanting for female company either, as his lady friend Elisabetta Canalis joined him for a recent visit to his Kentucky hometown.
