The last woman we heard Derek Hough was dating was Cheryl Cole -- but that's not who he was kissing last night in Canada.
The "Dancing with the Stars" pro was caught locking lips with 24-year-old Korean popstar BoA Kwon, AKA the Queen of K-Pop.
The story behind the photos makes them much less scandalous though -- as the two were actually photographed on the set of their new movie, "Cobu 3D." According to IMDB, the movie revolves around "A pair of star-crossed dancers in New York find themselves at the center of a bitter rivalry between their brothers' underground dance clubs."
Check out the set shots above!
