Katrina's boldest scene ever?

With Sheila Ki Jawani, Katrina Kaif has showcased a rarely seen avatar -- her sexy side. Though she has looked utterly delightful and ravishing in most of her films, she has never quite crossed the line and has been conservative in her dressing sense.

With the exception of Boom, she hasn't quite donned a two piece nor done a major kissing scene.

Little wonder, then, that this footage from Boom gets massive hits on YouTube.
