Actor Katrina Kaif's brand new ‘70s rockstar look', managed to attract a crowd of more than a thousand people even before the release of the track.

As soon as fans heard that Katrina was shooting for the song ‘Dhunki' at Agra Fort, a massive following gathered within a few minutes!

All the crowd and mob shots shown in the song are authentic - the only way Katrina could safely leave the venue at the end of the shoot was when a team of police was called to escort her out and take her away in a police van.

Katrina is all set to sizzle the screen in her smoking-hot grunge avatar in Mere Brother Ki Dulhan, co-starring Imran Khan and Ali Zafar.
