Katrina Kaif @ day & night with Two Heroes

Living the life of a top league heroine may look glitzy and glamorous from the outside but truth is, it is one of the most challenging things to do. This is something the angel of beauty Katrina Kaif would know properly as she is busy splitting her day and night with two different heroes.
Well, it is heard that Kats is currently busy with mighty heart Salman Khan for his movie 'Ek Tha Tiger'. This is happening during the day and in the second session, she has been preparing herself to pair up with Mr Perfectionist Aamir Khan for his film 'Dhoom 3'. Buzz is that Kats is also focusing on her body.
Sources say Kats is going to come up with some daredevil stunts and hard hitting fight sequences so she is getting trained by a team of experts from foreign countries. Despite doing the double shift, it is heard that this pretty girl glows like the morning sunshine. Wonder what is the secret behind that?
