Aishwarya ,Katrina ignore each other on Dhoom 3 set

 Actress Aishwarya Rai Bachchan and Katrina Kaif do not quite share the best the best of equations in bollywood,probably because of their common ex-factor:Salman Khan.

Apparently that was the reason that temperature dropped a few degree as the two uber hot beauties descended on the sets of Dhoom 3 in Chicago as the ladies share cold vibes.

Aishwarya was in the US recently to take her new role as the ambassador of UNAIDS,when she dropped in on the sets of Dhoom 3 to spend some quality time with hubby Abhishek Bachchan,who has been shooting for the film along with Amir Khan and Katrina

Her daughter Aaradhya Bachchan also accompanied Aishwarya to the set of Dhoom 3.How ever, the first person she bumped into was Katrina.Source said the two just exchanged a cursory polite smile and did not speak each other at all

Going back into the past ,interaction between Katrina and Aishwarya have always been restricted.Even at public events or award functions none of them has ever taken initiative to break the ice.In fact a couple of years ago when Katrina was requested to wish Aishwarya on her birthday,the actor changed the topic and refused to give a statement.
