Alia plans a birthday party for Ranbir

Alia Bhatt seems to have big plans for boyfriend Ranbir Kapoor's 38th birthday on September 28.

But wait, there's reason for a double celebration.

"It’s not just Ranbir’s birthday. It's also a second birth for his dad Rishi Kapoor," a source tells Subhash K Jha.

Rishi, who had been undergoing medical treatment in the US, returned to India on September 11.

"Ranbir and Alia decided to combine the two birthdays -- Ranbir’s and the new birth of his dad -- into one celebration,” says the source.

While the details of the big bash are still being worked out, we can tell you that the guest list will comprise the who’s who of the film industry. 

Now, what we'd love to know is if Sanjay Leela Bhansali will be invited.

Alia has been spotted visiting his office quite frequently, thanks to their collaboration in Inshallah.

He's also the director who introduced Ranbir Kapoor in the industry with Saawariya.
