Katrina Kaif is super busy.
In Thailand, she's reportedly shooting heavy duty action sequences with Salman Khan for 'Ek Tha Tiger' by day, and training by night for her forthcoming action sequences, which include hand-to-hand combat, with Aamir Khan, for 'Dhoom 3'.
"Aditya Chopra has flown in three special trainers for Katrina to get body-toned for her action sequences with Aamir in 'Dhoom 3'," said a source adding that the trainers have to make her look convincing as a combatant assassin in 'Dhoom 3'.
Kabir Khan is making the actress do other kind of stunts in front of the camera.
Said a source from on-location: "It's two completely different kinds of action discipline for Katrina on camera for 'Ek Tha Tiger' and off camera for 'Dhoom 3'.
And it's sapping her energies."
"Her metabolism is confused - as during daytime she is doing hardcrore raw action with Salman and in the night training for higholy sophisticated Jackie Chan kind of flips and somersaults for 'Dhoom 3'."
Luckily, for the over-exerted diva, she now has some reprieve on the 'Dhoom 3' front.
Apparently Aamir Khan has informed his producers that he is not quite ready for action.
Katrina remained unavailable for comment.
