The big screen reboot of Teenage Mutant Ninja Turtles has been delayed by several months.

Director Jonathan Liebesman's new vision of the crime-fighting reptile gang was set to hit cinemas in June, 2014 but has now been pushed back until August (14).

The decision comes just weeks after the film's star Megan Fox - who plays journalist April O'Neil - announced she is pregnant with her second child.

The movie also stars Will Arnett, Whoopi Goldberg and Alan Ritchson.
