(Subhash K Jha)

Katrina Kaif's dream of taking her mother, brother and sisters on a long vacation has to be put on hold for the time being.

After completing the current schedule of Ek Tha Tiger in Dublin, the actress will have to start preparing for her character in Dhoom 3 in the month that she had kept aside for her family holiday.

According to sources, Katrina has received an urgent return-to-duty call from Yashraj Films to not just learn some heavy-duty stunts but also exercise her vocal cords for her role in the sequel to Dhoom.

The actress will need to undertake para gliding lessons and a full-fledged singing course for the project. "Katrina has to go one up on the last Dhoom heroine Aishwarya Rai. That's a tall order in itself," informed a source.

Katrina, who had been planning to sing for Ali Zaqfar's album has yet been uninitiated into the realm of music. This will be the first time Katrina will sing for herself in a film.

Apart from the singing, Katrina it seems has a lot of pending work for the same film. She will need to discuss with Aditya Chopra and director Vijay Krishna Acharya about the look, body language, spoken language and attitude of her character in the project.

In fact, the singing portions of her character are now being worked out, waiting for Katrina to come down and lend her voice. Katrina remained unavailable for comment.
