Zero minus zero is zero. That's Adam Levine's not-so-romantic marriage math. "If you don't get married, you can't get divorced," he told the new issue of Nylon Guys. "Why couldn't we learn from the devastatingly low percentage of successful marriages that our last generation went through?" Despite his disinterest in saying "I do," Levine has been dating a steady stream of models of late, including his current flame, Behati Prinsloo.
