"The first day of shooting for Shimla Mirchi- with my Director Ramesh Sippy who is also doing a cameo in the movie (sic)," she tweeted Sunday.
The duo together gave hits like "Andaz", "Seeta Aur Geeta" and "Sholay".
"Shimla Mirchi" also stars Rajkummar Rao, who called it an "unusual film". He even expressed his excitement to romance Hema Malini on the big screen.
If reports are to be believed, the story is about how a single mother (Hema Malini) and her daughter (Rakul Preet Singh) fall in love with the same man.
