The makers of Sushant Singh Rajput and Sara Ali Khan starrer 'Kedarnath' is out with a pleasant romantic number after a devotional 'Namo Namo'. It is quite a festive number to be more specific, a pre-wedding number as Sara and Sushant as Mukku and Mansoor are aligned in each others path once again in someone's wedding.

Both wearing an ethnic attire grace each other with talking eyes and romantic gestures speaking louder than words. The duo is set to dance on this occasion and good vibes in context of their chemistry is well felt. Amit Trivedi has lent this happening composition to the song and Amitabh Bhattacharya has penned the lyrics. Dev Negi vocals is what makes "Sweetheart" compelling.

Kedarnath is touted to be an eternal love story from the backdrop of the flash floods that wrecked the temple town in June 2013. It is a mix of fine elements of love and religion, passion and spirituality and the combination is quite promising. The floods that took the lives of over a hundred thousand people is a powerful backdrop for this epic love story.

Helmed by Abhishek Kapoor, Kedarnath marks the debut of Sara Ali Khan. Produced by Ronnie Screwvala's RSVP and Abhishek Kapoor's Guy In the Sky Pictures, the film releases on December 7.
