From Hugh Hefner and Crystal Harris to Jesse James and Kat von D, see who else never made it down the aisle
Britney Spears and Jason Trawick
Engaged for more than a year, the pop star and the former CAA agent parted ways in January 2012. "I'll always adore him and we will remain great friends," Spears told Us in a statement. "As this chapter ends for us a new one begins," Trawick added. "I love and cherish her and her boys and we will be close forever."
