It's Valentine's Day! Time to get swept up in some movie romance.

The silver screen has some classic pairings that are so great they couldn't stop at just one film: Lauren Bacall and Humphrey Bogart; Katharine Hepburn and Spencer Tracy; heck, even Warren Beatty and Julie Christie.

But what about the new classics?

Drew Barrymore and Adam Sandler, anyone? What about Kate Winslet and Leonardo DiCaprio? And of course, Kristen Stewart and Robert Pattinson.

So nestle up with your sweetheart and click through our gallery of Best Onscreen Couples.

Maybe it'll inspire a little amorous picture show of your own. (Wink, wink.)
