Dating is pretty rough when you're young, but just try to imagine how bad it is when you are starting out in Hollywood. It has got to be hard to know who to trust, and honestly, you can't predict who is going to end up an A-list star. These celebs probably had no idea at the time that they were dating some of the biggest stars in the world.
Have you ever heard of these celeb couples?
1. Ashton Kutcher & January Jones
Kutcher had been making a name for himself on That 70s Show, but Jones had yet to make it big. She revealed that their relationship wasn't all roses. "He was not supportive of my acting," Jones said. "He was like, 'I don't think you're going to be good at this.' So, f--k you!"
