Any bollywood experts out there. Need help finding out who a certain actress is.

I was watching T.V. the other day and came across an actress, really want to know who she is. Unfortunately I am no bollywood connoisseur, nor do I frequently watch Indian cinema.

Now to get to the point, it was a movie scene, where an actor and actress were performing a certain song, I didn't recognise either of them.

The actress was dressed in yellow, I don't really remember the guy. They were at a train station or some sort of area like that, I do not remember if there were backup dancers or not. I would describe the actress as cute, small face, small nose, and fair skinned. I think it is a popular movie though. It was not raining, and no, I am not referring to Slumdog Millionaire. Apologies for not being able to provide more detail, I know I am basically giving you all nothing to go on, but I was just flipping through the channels and so I can't provide a better description.

If anyone knows this movie or the actress, please do let me know, it's killing me haha, need to solve this mystery. Thanks.
