Couples Who Should Work Together

Justin & Britney

In the past few days, fans have learned who will be guest mentoring the contestants on The X Factor this fall. Nick Jonas will assist Demi Lovato, Justin Bieber will lend L.A. Reid some swag and Marc Anthony was tapped by Simon Cowell. But who Britney Spears has selected remains a mystery.

Obviously the dream scenario is that Miss. Brit asks her ex, Justin Timberlake, to come in and impart some advice to her group. Yes, I know there's a greater chance of Christina Aguilera mentoring on The X Factor, but a boy can dream, can't he?

That got me thinking about 5 other dream on-screen pairings, comprised solely of real life couples!
