Impromptu singing at live events seems to be becoming a trend with Bollywood actors. After Alia Bhatt and Varun Dhawan, "Daawat-e-Ishq" actors Aditya Roy Kapur and Parineeti Chopra did the same at an event here. The duo was in Delhi Thursday for the launch of the title song of their upcoming movie "Daawat-e-Ishq", and they even sang the foot-tapping number for the media. The song "Daawat-e-Ishq" has a Lucknowi flavour with a blend of Qawwali and rock. The video of the vivacious song features Aditya, who plays a cook in the movie, dancing around a restaurant and trying to woo Parineeti with his 'Daawat-e-Ishq'. Both the actors look splendid in their Lucknowi attire. Talking about Lucknowi food, the actors shared that they are big foodies and enjoyed Lucknowi food all through the shooting of the movie. "Daawat-e-Ishq", releasing Sep 5, is a Yash Raj Films production. (Source: IANS)
