Justin and Cam connected in April 2003 after they met at the Nickelodeon Kids' Choice Awards and called it quits in January 2007. By the following May, JT had already linked up with Jessica Biel, but that didn't keep the pop star and Cameron from maintaining a healthy and happy working relationship. The former flames reunited to promote "Shrek the Third," in which they both voiced characters, and even shared a friendly hug and kiss (on the cheek!) at the Los Angeles premiere. Justin and Cam teamed up again -- this time on-camera -- in 2010's "Bad Teacher." "We had a great time," Cam told People magazine when asked what it was like working with her ex. "There really was no one else who was more perfect for this part. That's why he got the part." We just hope the couple's sex life wasn't anything like the awkward bedroom scenes they share in the film!
