India, Feb. 12 -- Filmmaker Anubhav Sinha teamed up with actor Ajay Devgn for the 2007 film, Cash. However, they never collaborated again, leading to reports of a tiff. Anubhav addressed the rumours in an interview with The Lallantop, saying, "We've never fought. He just doesn't speak to me and I have no idea why. Since the making of Cash, we haven't even met for me to tell you he ignored me or something. So, maybe, its just me overthinking.

But, its been about 18 years since we have spoken."...
