Lucky Ali has vowed not to sing in Hindi films, but he made an exception for Hrithik. He sang the super-hit 'Ik Pal Ka Jeena' in Kaho Naa Pyaar Hai. Lucky Ali and Hrithik Roshan are childhood pals. Rajesh Roshan convinced the guy to do a number for Hrithik in Kaho Naa Pyaar Hai.

People thought that after the craze of the song, Lucky Ali would continue to lend his voice for Hrithik Roshan. But the even the chartbusting success of the song has failed to change Lucky Ali's stand. Finally Hrithik and chacha Rajesh Roshan have roped in Kamaal Khan, of 'Oh Oh Jaanejana' number, for the new song in Hrithik-Esha Deol starrer 'Na Tum Jaano Na Hum'.

Will this number enjoy the same popularity as 'Ik Pal Ka Jeena' from Kaho Naa Pyaar Hai, is to be seen!
