The Date: February 20, 2012
The Moment: Chris collaborated with Rihanna on the remix to her song, "Birthday Cake," and, in return, she collaborated with him on the remix to his song, "Turn Up The Music."
Call It A Comeback: The cycle is complete. A few years ago, people thought Chris and his career would never survive the horrible incident that took place between him and Rih-Rih. Now? She's helped give his career a boost and helped him complete his biggest comeback of all. This guy. He just doesn't quit, does he?
