Sonakshi Sinha will no longer be competing against herself at the box office this June as the release of her next project 'Action Jackson', co-starring Ajay Devgn, has been postponed.

The film was earlier slated to release alongwith Sonakshi's other film 'Holiday', opposite Akshay Kumar. 

Confirming the news, director of Action Jackson, Prabhu Dheva said, "We haven't decided yet (about the release date). We are in no hurry to release. I have completed 80 per cent of the shooting. I am currently working on the post production of the film and the script for my next with Akshay Kumar."

However, rumour has it that though 'Action Jackson' has made way for Holiday, it's actually 'Singham 2' that caused the delay. 

'Singham 2' also stars Ajay and it is believed that the actor asked Prabhu to push back his film so as to create space between the two action movies. 

'Singham 2' hits the theaters on August 15 and reports suggest that 'Action Jackson' may now release in 2015.

However, the new release date for 'Action Jackson' has not been announced yet.
