Anurag in an earlier interview had stated that Kalki and he will remain good friends despite being separated.
Though there are strong rumours that Anurag is dating his 'Bombay Velvet' assistant director, Sabrina Khan and Kalki is pretty much aware about it.
Kalki supported the team whole-heartily and posed with her ex-husband for shutterbugs. The two are not divorced yet but it looks like they are trying hard to get things work out between them.
This is Bollywood you can expect anything!
