Rob and Kristen on Top-Grossing On-Screen Couples

5. Robert Pattinson and Kristen Stewart
$1.8 billion

Rounding out the top five are Robert Pattinson and Kristen Stewart in the Twilight movies. While romance might take a backseat to action in many of the movies on our list, it's the driving force in the Twilight films. It doesn't hurt that Pattinson and Stewart are also a couple in real life. So far the movies have earned $1.8 billion at the global box office. The last book, Breaking Dawn, has been divided into two movies. The first will hit theaters this coming November.
