They are all set to work togethe for the 4th installation of the "Golmaal" series titled as "Golmaal 4".

Sources close to the director reveal that actor Ajay Devgn is now very much a part of 'Golmaal 4'  and  that Shetty will start working on after he completes Shah Rukh Khan and Kareena Kapoor starrer 'Chennai Express'.

According to some sources, the actor and the filmmaker had a difference of opinion over the way 'Singham' was shot. "However, now all is well between Devgn and Rohit. They are as thick as before. The shoot of 'Bol Bachchan', a project they are working together, is going smoothly," reveals the source.

With Ajay Devgn returning to the project, the 'Golmaal 4' cast remains more or less intact.  Actress Kareena Kapoor, who also happens to be a Rohit Shetty favourite is also slated to be a part of the film.
