She is judging Sony TV's ongoing reality show 'K for Kishore', an ode to the maestro.
'I stopped working because I was busy taking care of Sumit, who was very young at that time. Now he has grown up. When I heard about this show, I could not stop from being a part of it,' she explained.
Of the 12 contestants vying for the title of the music maestro's most deserving successor, Promod Rampal is in the reckoning.
'The contestants are very good. Some of them have performed well. Pramod is quite close. He has a good voice and sings very well,' said Leena, who acted in hits like, 'Humjoli' and 'Manchali'.
Other judges include music director Bappi Lahiri, playback singer Sudesh Bhonsale and Kishore Kumar's elder son Amit.
Asked about the role of talent shows in churning out new talents, Leena said: 'Shows do not produce talent, but they help discover talent.'
