Rumours have been rife that the 'Raabta' co-stars, Sushant Singh Rajput and Kriti Sanon are much more than friends and are quite serious about each other. But when Sushant's co-star Kriti was asked to define their bond, the 'Dilwale' actress said that Sushant kept her on her toes during the shooting of their new film 'Raabta'. Ever since 'Raabta' went on floors, the grapevine relentlessly insisted that Sushant and Kriti have been dating. But Kriti rubbished all the rumours, saying that it is better to ignore them. Directed by Dinesh Vijan and produced by Homi Adajania and T-Series, Raabta is scheduled to release on June 9.
