Karan Johar likes to keep his Twitter account free out of controversies. So it was surprising to see him lash out at someone he didn't wish to name.

'Using their hired PR machinery and hiding behind so called "friends" to get news into tabloids is nothing but spineless and lame!!! Some people need to wake up and smell the KOFFEE!!! Get a reality check before its too late!!! Grow up!!! and dont mess with goodness,' Johar tweeted.

Was he referring to Priyanka Chopra's interview to a tabloid, where 'sources close to her' lashed out to star wives, and a certain powerful producer-director who could make or break careers? Priyanka's sources also tried to put to rest rumours of her alleged affair with Shah Rukh Khan. While we figure out what exactly angered Karan Johar, check out the still from Kunal Kohli's next film Teri Meri Kahaani, starring Priyanka and Shahid Kapoor.
