Ranveer Singh bonds with Katrina Kaif: Should Deepika Padukone be worried?

Ranveer Singh and Katrina Kaif seem to have become the new besties in Bollywood. The actor, currently in a relationship with Deepika Padukone, recently welcomed Katrina on a photo-sharing website with a video message. 

What's so special you'd ask? Nothing much, except that this is one of the many instances in recent times when the duo has evidently been quite friendly with each other. This, given that Katrina and Deepika are not the best of friends.

Over the last few months, Katrina has been spotted hanging around with Ranveer a couple of times. Reportedly, they were together at Shahid Kapoor's birthday bash in February. More recently, they were at filmmaker Zoya Akhtar's house for a casual get-together. And incidentally, Deepika wasn't on the scene on both occasions. We wonder what's cooking!
