Bollywood actors Shahid Kapoor and Sonakshi Sinha along with director Prabhu Deva shook their legs to a song at the music launch of their film, "R... Rajkumar" at JW Marriott Hotel, Mumbai.

Featuring Shahid Kapoor and Sonakshi Sinha in the lead roles, "R... Rajkumar" is directed by Prabhu Deva and produced by Eros International and Viki Rajani. It is scheduled for release on 6 December.

"I used to think that I'm an okay dancer till I started working with Prabhu (Deva) sir. And he used to come with this angelic, serene smile on his face to rehearsal everyday. When he would show me (the steps) I used to be amazed and then he used to say, "do". After that, I would rehearse for four to five hours. I mean he's been very kind saying that it was easy. No it wasn't. He's worked very hard to make me dance like this," ANI quoted Shahid as saying at the music launch event.

"R... Rajkumar" has music scored by Pritam Chakraborty. It has five songs - "Gandi Baat" sang by Mika Singh and Kalpana Patowary, "Saree Ke Fall Sa" by Nakash Aziz and Antara Mitra, "Mat Maari" by Kunal Ganjawala and Sunidhi Chauhan, "Dhokha Dhadi" by Arijit Singh, and "Kaddu Katega" by Antara Mitra.

The official theatrical trailer of the film released last month has got over 37 lakh hits till date. It promises stunning action scenes from lead pair - Shahid Kapoor and Sonakshi Sinha.
