Katrina: JJ is an emotional musical abt a somewhat detective

This year, Katrina Kaif might have had just one release, but like beau Ranbir Kapoor, will have several in 2015. From Jagga Jasoos with RK to Phantom with Saif Ali Khan and Fitoor with Aditya Roy Kapur, Kat's gonna be busy all year.

She won't clarify if her character is supposed to be older than RK or not, saying she would "ask everyone to keep guessing."

And Ranbir? "All I can tell you is that he plays a sort of detective but not in the traditional sense,"

she answers.

Calling JJ an emotional venture, she confirms that the film is a musical. "People have asked me if there are 20 songs in the film. I think that's something totally insane. I cannot tell you how many songs are there but it is a musical film in the traditional sense."

Okay, then!
