Since the announcement of 'Dhoom 3', the movie had been a favourite of gossip mongers. After much speculation about the cast, the banner Yash Raj Films finalised Aamir Khan, Katrina Kaif, Abhishek Bachchan and Uday Chopra.

Talks had been that Katrina has started to shoot for the film, getting trained for some high voltage action sequences. However the production team had rubbished it. Later it was also said that the British beauty will sizzle in a bikini - but then Katrina put down strict condition that she won't be wearing the two-piece.

Now latest we hear that Katrina will be doing some underwater stunts for few action scenes in 'Dhoom 3'. Earlier the actress had done scuba diving in Zoya Akhtar's 'Zindagi Na Milegi Dobaara'. So it wouldn't be something new for the ravishing Kat and she is said to be very excited and looking forward to do the water diving part again, this time for YRF's flick.

Wait there is more.... Katrina will also croon for her character in 'Dhoom 3'. While she will be lending her voice for actor-singer Ali Zafar's album, this will be first time the actress will sing for a film.

Hmmmm, looks like this movie bring out Katrina's hidden talents....
