Actress Sonam Kapoor has managed to mesmerise her fans with her stylish avatars at most of her appearances, but there's a special beauty secret that she has been guarding from everyone.

She is said to be hiding the secret in a Mystery White Box lately, and she will reveal it sometime soon.

It is perhaps a new endorsement deal that Sonam has bagged for a new beauty product, but details of it are currently under wraps.

Sonam's mystery box is likely to be revealed towards the end of this month.

Meanwhile, it is her style squad -- designer Manish Malhotra and ace photographer Jatin Kampani -- who are ensuring that she looks her best always. They have been giving her fashion and beauty tips.
