Happy 32nd birthday to you Joseph Gordon-Levitt! The 500 Days of Summer actor has only gotten better looking as the years have gone on. I feel like I have seen Joseph Gordon-Levitt grow up, even though he is older than me. I remember watching him on Rosanne and 3rd Rock From the Sun late night on a school nights. Next thing I knew, he was tearing up the big screen with 500 Days of Summer. I love Joseph Gordon-Levitt and definitely don't mind looking at him. He is such a cutie! Here is a gallery filled with photos of him from young to old! Like I said before, you have only gotten better looking with age.
