Sanjay Leela Bhansali has moved on to his next film, Padmavati.
The first song recording by Shreya Ghoshal is also underway.
The 32-year-old singer, who won all the major music awards for the Deewani Mastani from Bajirao Mastani, took to Twitter to share the news of recording a "landmark song" of her career from one of the "outstanding" compositions by the 53-year-old filmmaker.
'Recorded a landmark song of my life today. Soul satisfying emotional joy ride. I live just to be able experience such moments! #powerofmusic,' she wrote some times back.
In another tweet Shreya wrote, 'Wondering which song! What outstanding compositions Sanjay Bhansali sir has made for #Padmavati. Sang with all heart!'
During the media interaction at IIFA, Bhansali hinted about his next project saying, "No time to party. I would get back to the next one (project) and work hard."
It was reported last week that music director Shreyas Puranik, who was supposed to work on Padmavati, confirmed with a tweet that Deepika Padukone would star in the magnum opus.
However, on Sunday morning, Puranik's account could not be found on Twitter and rumours were rife that he had deleted it.
It is also reported that after the success of Goliyon Ki Raasleela: Ram Leela and Bajirao Mastani, the upcoming project, which is supposedly based on tyrant emperor Alauddin Khilji's obsession for Padmavati, the queen of Chittor, will mark the third collaboration of Bhansali-Deepika and Ranveer Singh.
As per the rumour mills, Masaan actor Vicky Kaushal has been finalised to play Dips' husband.
Bhansali had earlier directed an opera of the same name and theme, which was widely appreciated in Paris.
Prakash Kapadia, who scripted Bajirao Mastani, has reportedly been roped in to write Padmavati.
