Priyanka Chopra, star of Dil Dhadakne Do and singer of its title track, made the most recent announcement on Twitter, with a photo of her co-star Farhan Akhtar who also duets on the song.
Both actors are accomplished singers with musical careers of their own. This will be Priyanka's first foray into singing playback - Farhan has sung in films like Rock On!! and Zindagi Na Milegi Dobara.
Their co-star Anil Kapoor promises it will be a treat:
Last evening, all four Dil Dhadakne Do Mehras tweeted a countdown to the song, just as they had to the trailer some days ago.
