Ryan Seacrest and Julianne Hough
Seacrest out. The American Idol host and actress pulled the plug on their two-year relationship in March 2013, with their busy schedules contributing to the split. "Honestly, their schedules were too hectic," a source told Us. "It just got to be too much. I think they both just sort of knew they couldn't do it anymore."
