Confirming this, Dia said: "We've finally zeroed in on a date for our wedding. It's 18 October. That's the date when Sahil and I will be married."
The wedding will take place in Delhi and will be attended by the couple's family and close friends only. Dia is likely to later host a lavish reception in Mumbai for her friends from the entertainment industry.
Sahil's family is largely based in Delhi, and so, their nuptials are due to be held in the capital.
"It was the two families' decision to have the wedding in Delhi on the chosen date," said Dia.
