The Sitch: A Nicholas Sparks romance novel turned Miley Cyrus romance film turned real-life romance. It's truly a multiplatform love affair.
Suggestion: These two seem to be doing just fine, what with the "Last Song" press tour where Miley gets to indulge in talking about their love in both the movie and real life (she's the polar opposite of K.Stew). But soon enough, Miley's publicity purposes for the relationship will be through. Then they're entering murky, non-marketing-exploitative waters. Might I suggest entering into a five-movie contract together? Would probably be more foolproof for Miley than, you know, a marriage contract.
