In a joint statement last month, the couple said they were separating. "Me and Kalki are separating. We are taking time off from each other to figure things out. We are not divorcing," it said.
When asked by reporters at a film event here last evening if all was well with his marriage, the 'Black Friday' director pleaded to be left alone on this issue.
"I don't think this is the platform (he was present at the trailer launch of 'Hasee Toh Phasee') to talk about it. I would not like to talk about my personal life at a public platform."
This was apparently Kashyap's first appearance at a film event after they separated in mid-November.
Kalki, an Indian of French descent, and Kashyap, who has helmed films like 'Gulal' and 'Gangs of Wasseypur', fell in love while working on 'Dev D' in 2009. The two got married in April 2011.
Kashyap was previously married to Aarti Bajaj with whom he has a daughter, while it was Kalki's first marriage.
