It is a known fact that John Abraham and Salman Khan are not the thickest of pals. Way back in 2006, the two stars apparently had a showdown during a concert.


A few years after that, John had made a statement saying that his Madras Cafe' is more realistic than Salman's spy thriller Ek Tha Tiger. Now, it seems that the two hunks are gearing up for another clash this September.


A few days back, John Abraham had announced on Twitter that his upcoming film Welcome Back is slated to release on September 4. A couple of days later, Salman took to Twitter to write, "Back off… HERO coming on 4th September."


Wonder what 'Action Abraham' has to say about this now…
