Kangna Ranaut is following in the footsteps of stars like Shah Rukh Khan, Aamir Khan, Salman Khan and Juhi Chawla. The curly haired beauty will be seen singing a romantic number in the Rakesh Roshan-directed movie ‘Krrish 3’. Composer Rajesh Roshan is full of praise of Kangna for hitting the right notes in the movie, in which she plays a negative chracter. “Kangna is a born artist. There are praises for her from me. She has sung such a tough song in the film… to sing such a song, a full-fledged romantic song, it is a big thing,” Rajesh told IANS. Talking about the music of the supehero film, which stars Hrithik Roshan in the lead role, he said that it was tough as his director-brother Rakesh had set high standards. The composer also added that one song took about a month to be made and five to six days to mix.
