SpotboyE.com has it that the two stars had a brief but cordial meet after the auction was over.
For those who've come in late, rumour had it that Katrina's growing friendship with Hrithik during their shooting schedules of Bang Bang in Europe had unsettled Ranbir and he had even met Roshan Jr on his return for a quick chat. Post that, Katrina-Ranbir and Hrithik had maintained a safe distance from each other.
So who broke the ice, we asked? A source says, "Ranbir made the first move. He smiled and walked a few steps towards Hrithik, who reciprocated rather well. They hugged and greeted each other."
All's well that ends well...
