3 days ago SRK hung out with Ritesh Sidhwani on the sets of Chennai Express. And today he has a meeting with Ritesh (as srk tweeted). I think they might have met to talk about Don 3. Now srk hanging out with ritesh on the sets of CE might have been put off as a one off hang out between two friends (even though it doesn't seem srk and ritesh would be that close of friends for Ritesh to just drop in to talk to srk on the sets of CE). But then today they have a meeting. There must be a special reason behind these interactions and I think plans for Don 3. For those that don't know Ritesh Sidhwani along with Farhan Akhtar is behind the production Excel Entertainment that produced Don 1 and Don 2.
