^ They are cordial when they meet but certainly not friends anymore. Anushka herself said that in KWK 2014 (her episode with Anurag Kashyap). Their breakup was bitter and they were not on talking terms until they did DDD. So many articles and blinds were published about their bitter breakup.
I remember watching a report on Zoo m tv, about 2013 or 2012 filmfare nomination bash, RS and Anushka ignored each other eventhough they were sitting nearby. After the party the rep orter asked RS why he did not talk to her and he replied he did not know she was there. Also RS in an interview said that when Zoya suggested Anu's name for DDD he said he was fine working with her if she is ok with working with him and he was surprised when she said yes.What I gather from this is, they are just work colleagues and when they meet they catch up.
