Ranveer Singh and Vaani Kapoor share a sizzling chemistry in ‘Befikre’. Singing paeans about his co-star, Ranveer says, “Vaani is a sweetheart. She brings great energy to the sets. It is exhilarating that there is someone else’s energy that infects me and energises me. That happened to me from the very first day I shot with Vaani. She is always in the moment, works hard and is very passionate about acting and films.” ‘Befikre’ is a love story set in Paris, directed by Yash Raj Films’ scion Aditya Chopra. The Bollywood movie will release on December 9.
