Whats Common Between Arjan and Priyanka

It seems that both the stars from Madhur Bhandarkar's Fashion are often seen discussiong martial arts on the sets. Incidentally, Priyanka got herself trained in martial arts for Drona, a film which she is doing with Abhishek Bachchan. A source from the film unit says, "Priyanka was informed by someone on the set that Arjan is a Taekwondo expert. She takes special interest in knowing various forms of martial arts. During the shot breaks they would talk about how she did her own stunts in the film, and how Arjan practices Taekwondo on a regular basis." Priyanka was not aware of the fact that Taekwondo is a blend of Shotokan Karate with other Chinese and Korean martial arts. But finally, she got all information from Arjan and now she can also be called an expert. So now we won't be surprised if we see Arjan and Priyanka in a martial arts film.
