1. John Legend & Chrissy Teigen
John and Chrissy are probably one of Hollywood's favorite couples, and even though they surely seem madly in love, it wasn't love at first sight for the power-couple. They met on the set of John's "Stereo" music video, and Chrissy admits that they did hook up. However, it took a few years for them to settle down and commit to forever. John admits that he's always been cautious when it comes to relationships, and Chrissy had no problem playing it cool along the way.
