Justin Guarini Can’t Resist An Audience

Knight Ridder reports ‘American Idol’ runner-up Justin Guarini has been making cameos at Studio, an unglitzy karaoke club in South Beach. Studio owner Louis Rosenthal said Guarini promises to be back this weekend. “He’s been a regular here since before American Idol, when he was working around South Beach clubs,” Rosenthal said. “He’s a great kid. And the show hasn’t changed him one bit. Well, his hair is curlier and longer.”
