The Arjun birthday bash is still the talk of the town and these pictures will tell you why. It's the Ranveer, Ranbir, Katrina partying together without Deepika Padukone. For those not in tune, Deepika is Ranbir's ex, but Ranveer's current flame. Kat is with Ranbir now. Confused? Well the stars were not, as the pics show.
