The good-looking couple have been dating for over 5 years now.
Dia Mirza wore an yellow anarkali suit for her mehendi ceremony which took place on Thursday night. Her fiance, filmmaker Sahil Sangha looked dapper in a red kurta and nehru jacket.
The couple, who have been dating each other for the past five years, will be tying the knot in Delhi on Saturday.
Dia shared the gorgeous Mehendi picture of her and Sahil on Twitter.
Earlier in the day she also tweeted "Mehendi hai rachne wali(sic)," indicating that she was looking forward to begin the celebrations.
Dia had started planning her wedding soon after the film 'Bobby Jasoos' produced under the Born Free Entertainment banner - which she co-owns with Sahil.
"Sahil and I will get married this year and we are looking forward to our future together...we will start planning our wedding from next week," Dia had said.
"If I tell you everything right now then there would be no surprise. But you would not need to play detective. I will get married in India itself in October," Dia had added coyly.
Dia had to defer her wedding date with her filmmaker beau Sahil because of his uncle's ill-health.
