Christian Slater might be a screen icon, but he is surprised by the attention reality stars get in Miami. At an Art Basel screening of Adrian Grenier’s documentary “Teenage Paparazzo,” Grenier, Slater and World Red Eye photographer Seth Browarnik participated in a panel discussion about how social media and paparazzi affect celebrity. Slater related that he was recently picking up Advil from a drugstore when he saw a group of men with cameras approaching. He said, “I thought they followed me because I tweeted about the elections and was receiving a ton of criticism, but then I looked and realized that the Kardashians had just pulled up next to me — they weren’t interested in me at all.”
