Luke Bryan is feeling the full effects of being a TV star. Since appearing on the season 1 ABC reboot of American Idol, Luke tells us he has learned just how powerful network television can be. “Well I mean the main thing is you gotta understand there's a segment of the world that doesn't even listen to the radio. They just watch TV, so people who watch TV just learned who I was, so, yeah, I mean, when I hop in a cab somewhere and a foreign cab driver's like, 'I know your voice . . . Ooh, you're a judge on American Idol,' that's when you see there's just a whole nother segment of people.” .
