From the fans to the stars to the security staffers, everyone loves Comic-Con!

Over the weekend we caught up with some of our favorite actors at the show in San Diego, and not only did they pose for the cameras, but they spent plenty of time mingling with the crowds.

Some celebs, like Will Smith and Jared Leto signed autographs and shook hands, while Margot Robbie took things one step further and planted a smooch on one lucky fan -- while Cara Delevingne caught the whole thing on her iPhone! Cara also had a pretty hilarious exchange with a security guard working the event, and she was giving out lots of hugs. Awww, we love it when A-listers leave their fame at the door!
