Shah Rukh Khan and Ajay Devgn had much of a showdown a couple of years back, when both the actors were set to clash at the box office. While SRK starrer Yash Raj Films' 'Jab Tak Hai Jaan' was all set to release, Ajay Devgn released his film, 'Son of Sardaar'. But now it seems that things have become better between the two. Ajay and Rohit Shetty's 'Singham Returns' will hit the theatres on August 15, and along with it will be attached a mega trailer of 'Happy New Year'. However, that is not all as SRK even congratulated the team of 'Singham' for the film.
