Channing Tatum and Jenna Dewan-Tatum
Characters: Tyler Gage and Nora Clark
Movie: Step Up (2006)
As Jenna Dewan tells it, when she first met Channing Tatum on the set of Step-Up, he was ever the gentleman. Later, however, it turned out that while they ran lines alone, he had one thought on his mind: her stanking-ass breath.
In the movie, Tatum plays the boy from the wrong side of the tracks to Dewan's overprivileged prima donna in the making. It's the classic hip-hop versus modern dance dilemma. After the film was finished, the couple began dating, then married a few years later. Turns out Dewan's breath wasn't repellent after all.
