Kunal is currently filming "Guddu Ki Gun" in the city of joy, while his lady love is back here from Ludhiana after shooting for a film based on 1984 riots.
"Happy birthday Kunal Khemu. It's a Sunday. It's pouring in Kolkata. Time for pancakes I say," she posted on Twitter.
It is Kunal's maiden visit to Kolkata and he was looking forward to "a fun shoot in this amazing city" a few days back.
