Sonakshi Sinha-Arjun Kapoor in love?

Is this true or is it a publicity stunt. Sources say that Tevar couple Sonakshi Sinha and Arjun Kapoor are more than on-screen couple. They are often seen dining and seeing movies together. Sources say that after the shoot the couple is seen uttering sweet nothings in each other's ears. Bur remember even Alia and Arjun were linked before the release of 2 States. But this time, the couple is serious, say the sources.
