Allie and Noah, Jack and Rose, Ron and Hermione—the Hollywood machine runs on the engine of "happily ever afters." But the real-life relationships that spring up in the dream factory are the result of long hours, close quarters, and an absurdly attractive workforce—and they aren't generally known for their stability.
On the contrary, Tinseltown's behind-the-scenes love stories are more often blink-and-you'll-miss-'em flings that start illicitly (Mr. And Mrs. Smith, anyone?) and end ignominiously (a la K. Stew's affair with her married director, which dashed dreams of Rob and Kirsten's fairytale ending for a generation). So, yeah, when you look at most celebrities' romantic track records, it's easy to start wondering if maybe Hollywood used up all its magic on silver screen love stories, and there just isn't any left for real life.
But then you catch a glimpse of Tom Hanks and Rita Wilson canoodling on the red carpet like they just met—after almost 30 years together!—and you remember magic wouldn't be magic if it had limits. You remember that the greatest love stories are always the ones that happen against all odds. So, not only is true love possible in the unlikeliest circumstances—it's the most inspiring love there is.
So, with that in mind, we rounded up the best sex, love, and relationship advice from Hollywood's most swoon-inducing couples. After all—if these stars can deal with sex scenes and separations galore for decades—they can probably teach us a thing or two about making a relationship last IRL.
