Shahrukh Khan and Katrina Kaif filming in London

After being a die hard fan of Shahrukh Khan, how exciting was it for me stumble him and Katrina Kaif filming for Yash Raj's yet untitled romantic film at Westminster. Not so sure how i felt about that the film crew did treat all onlookers like criminals and didn't let us take pics (i did) but it was a rather dramatic affair. Then again, this is Bollywood!
