We first saw them together on screen in Raj Kanwar's 2006 dud, Humko Deewana Kar Gaye.
And it was love at first sight -- on screen that is.
Akshay Kumar [Images] and Katrina Kaif [Images] share good onscreen chemistry, which spurred two more hits -- Namastey London [Images] and Welcome, and a third film in the making, Singh is Kinng, which will release August 8.
Off-screen too, the duo seem to get on like a house on fire as evident from their comfort level at Wednesday's Indian Premier League game between Delhi Daredevils and Bangalore Royal Challengers.
The two looked at ease with each other. In fact, they looked so comfortable that we can't help but wonder...
Should Salman worry? What do you think?
