Rumour has it that the director is planning a film with Shahid, instead of best friend Ranbir

Is Wake Up Sid director Ayan Mukerjee working with Ranbir 'Sid' Kapoor again or is he making a film with Shahid Kapoor?

It's the most talked-about dosti in the film industry after Shah Rukh Khan and Karan Johar. Mukherjee, hitherto known as Kapoor's best friend, is now being seen with Shahid. The buzz is that Mukherjee has decided to direct his next film, with Shahid instead.

An actress who is close to Kapoor agrees. "Who has the time to cultivate friendships without a professional agenda? Do you think Shah Rukh and Karan would have time for each other if they weren't working together?"

Mukerjee was present for Shahid's birthday bash two weeks ago. "They go out for movies and hang out in each others' homes, " a source added.

Kapoor, who was shooting for Rockstar in Kashmir the past few weeks, is oblivious of the developments. A friend of his said, "Ranbir is not sentimental or possessive about his friends. If Mukerjee chooses to work with another actor, Ranbir is hardly going to sit and mourn the loss. "

Karan Johar who is producing his protege Mukerjee's second film, is blase about the director's new dosti.

"Why read hidden agendas into every relationship? If Ayan is hanging out with Shahid, they could just be bonding without work on their mind. As far as I know Ayan's next is with Ranbir. Until Ayan tells me otherwise, I've no reason to think his plans have changed. "
