B-Town is buzzing with the blooming friendship between Ranbir Kapoor and Kangana Ranaut.

They caught up with each other recently, but their mutual admiration goes way back. After Queen (2014) released, RK was so impressed with Kangs that he expressed the desire to work with her.

Kangana has always wanted to do a Raju Hirani film, and with Ranbir in Hirani's biopic on Sanjay Dutt, there is speculation that the two will team up.

But once-upon-a-time good pals Dutt and Kangana had a fallout after their film Rascals (2011) released. So will Dutt give the green signal for Kangs to be part of his biopic?
