At the music release function of the film, Rekha said co-actor and singer Vasundhara Das had inspired her to sing after a long time.
Debutant director Amar Butala said that the legendary actress had probably lent her voice to a song in Hrishikesh Mukherjee's 'Khubsoorat' two decades ago.
The music release function held at a five star hotel on Thursday night began two hours late. But, the media did not mind and they created a flutter when the style icon made a grand entry.
The photographers were falling over each other to capture each and every mood and movement of the Bollywood diva in their lenses. But, she disappointed the mediapersons by leaving the venue as soon as the function was over.
Speaking after the music release function, Rekha said she enjoyed working with the cast and crew of the film.
Mahima Chaudhary, Kim Sharma, Vasundhara Das, Ashmit Patel are the other cast members.
Butala said the story is about four women who belong to different age groups and different walks of life but are best friends.
He said 'Kudiyon Ka Hai Zamana' is a fun and warm film about how best friends can sometimes be worst enemies. ''It is all about friendship and true love,'' he added.
''The women in my film have distinctive personalities and yet there is a rapport between them. They have their own way of dealing with a situation and in portraying this part of the film, I think have have done justice to the female psyche,'' he added.
