Few months ago, there were rumours of Hrithik Roshan and Karan Johar's friendship hitting the rock bottom, reason being Duggu walking out of KJo's most ambitious project 'Shhuddhi'.

Apparently, the two were not even on talking terms. But now it seems like the two have forgotten their differences and have decided to patch up.

The filmmaker is heard to be attaching the trailer of his much awaited film 'Ungli' with 'Bang Bang'. This film is directed by Rensil D'Silva and stars Emraan Hashmi, Kangana Ranaut, Randeep Hooda and Sanjay Dutt.

Confirming the news Apoorva Mehta, CEO of Dharma Productions said, "We are releasing our film's trailer with Bang Bang."
