**Chrissy Teigen** <br><br> I'ts hard to imagine a world in which Chrissy Teigen's Twitter account wasn't taken as gospel, and we didn't have her and John Legend's love story at the front of our minds, but when she appeared in *SI*'s 2010 Swimsuit Edition, it was as a complete unknown. She went on to win Rookie of the Year for 2010 and star in four subsequent issues of the magazine, even landing a cover in 2014.
