Singer and fellow parliamentarian Babul Supriyo came up with the idea and soon they would record a duet song at a studio in Mumbai.
"As a singer I have been discovered by Babul... the whole credit goes to him," the 67-year-old actress told reporters here.
She said the concept of this song was interesting. Hema starred opposite Dharmendra in 1977 film 'Dream Girl', directed by Pramod Chakravorty. Sung by the legendary Kishore Kumar, the film's title song, which rojected her as a dream girl, was an instant hit.
Explaining the concept of the song, Babul said it was about how today's youth was trying to pull back the dream girl into this era.
"She comes back to show today's girl what a dream girl is all about - in terms of natural beauty, beauty of the mind, no tantrums, simplicity, humility and everything you could attribute to her," he said.
"A dream girl is not someone who can be kept in a showcase. A dream girl is today's material woman who can handle everything. It is a Bible for a young woman to understand how happy a woman can be when she takes up those difficult challenges," he said.
To be produced by Saregama, the lyrics of the new song were being written now and it would be a bilingual one in Hindi and Bengali.
Babul said they would like Prime Minister Narendra Modi to launch the album in Delhi.
"If it can be launched by the Prime Minister, why not? We are dreaming about it," the BJP MP from Asansol said.
The lyrics of the album would be by Srijato and music composition by Indradip Dasgupta.
Besides the 'Dream Girl' song, Hema Malini, the BJP MP from Mathura, is also re-recording two Bengali songs to which she had rendered her voice 41 years ago and recalled how Kishore Kumar had motivated her to record the songs.
"Recording it after so many years... the same song in the same scale is very difficult. Your whole personality changes, voice, scale everything changes," she said.
Babul said they have recreated the old songs to make it contemporary with modern musical tracks using guitars etc.
The songs were written by Mukul Dutta and set to tune by none other than Kishore Kumar.
All these songs were slated to be released by Valentine's Day next month.
Hema, who has donned multiple hats, said the eagerness to learn new things was still there in her and now she wants to learn more of Sanskrit, learn how to play the sitar and do a little bit of painting as well.
