"Our film 'Yeh Jawani Hai Deewani' starts this month... directed by Ayan Mukherji and stars Ranbir-Deepika (Padukone) and Aditya Roy Kapur and Kalki (Koechlin)," Karan confirmed on micro-blogging site Twitter.
Music director Pritam will compose the music for the movie. Mukerji created a stir with his directorial venture "Wake Up Sid", about a guy who falls in love with an older girl, played by Konkona Sen Sharma. The romantic comedy with the unconventional pair turned out to be a big hit.
