Rumoured ex-flames Anushka Sharma and Ranveer Singh are paired opposite each other in Dil Dhadakne Do. However, the more interesting twist is the fact that the actress has done her first item number in the film directed by Zoya Akhtar. Sources said the song is called Swing and even though some other members of the ensemble cast that includes Priyanka Chopra, Farhan Akhtar, Anil Kapoor and Shefali Shah are also seen in the same song; the spotlight is on Anushka who is performing her first full-fledged item number. Producer Ritesh Sidhwani remained unavailable for comment.
