What a lovely couple they make!
Well, they haven't confessed to be dating each other. But isn't it so obvious they are?
The love affair started on the sets of Koffee with Karan when Sara confessed she had a crush on Kartik.
And Imtiaz Ali got them together for 'Love Aaj Kal' sequel.
And then it was -- Pyaar huya, ikraar huya -- all along.
Sara and Kartik's film is scheduled to release next year on the Valentine's Day.
