Alisha had sang for Priyanka in 2005 film "Karam" and the song "Tinka tinka" became synonymous with the actress' sizzling femme fatale image.
It's a song that Priyanka was meant to sing in her own voice. However, the music deal for her international album prevents Priyanka from singing in any other form, medium or capacity.
Alisha, we believe, was roped in on Priyanka's recommendation.
"I've been keeping away from playback singing. There is nothing that enthuses me at the moment. I am happy to be away from playback singing in my little paradise in Alibaug where I stay," said Alisha who has been occupied with looking after her ailing father.
Rajesh Roshan met Alisha in Alibaug and offered her the number in "Krissh 3".
Said Alisha, "I couldn't say no to Rajesh. I have a very high regard for his melodies. And the song was for Priyanka. I enjoy singing for her. I remember her telling me after I sang 'Tinka tinka' that she had once come backstage with her father to meet me in her home-town Rae Bareilly where I had gone to perform.
"Priyanka told me she had to wait for hours to meet me. That was sweet of her. And I loved the way she put forward the 'Tinka tinka' song on the screen."
Priyanka made her singing debut with international single "In My City".
About the actress' own singing career that took off recently, Alisha said: "I really like her music video. But I wish she would choose her songs a little better."
The singer feels the future of the music industry lies in the revival of non-film albums.
"Even today I am recognised for the 'Made In India' album. I'm looking at doing an album of my own," she said.
