Katrina Kaif has a new nickname, courtesy boyfriend Salman Khan. A source from the sets of Yuvraaj called to inform us that Salman calls her KK. Yes, we know it sounds like a villain's name from the eighties' but she seems to like it. In fact, KK (here we go) has taken such a fancy to the new nick that she insists everyone around her to call her that." Hmmm the other KK (Kareena Kapoor) must be doing a slow-burn!
