UPDATE: Fox was photographed on the "TMNT" set with co-star Will Arnett in Los Angeles on Tuesday, April 1. The 27-year-old -- who gave birth to her second child with husband Brian Austin Green on Feb. 12 -- wore tight jeans, a T-shirt and a zip-up hoodie to get into the role of April O'Neil.
"She's a kick-ass April," Arnett told IGN. "Megan did such a great job. There are some great sequences that she has and that we both have together that are really high octane where we're fighting all sorts of bad dudes."
Geeks of Doom reported the Michael Bay-produced flick is currently in reshoots, but the August 2014 release date won't be affected.
UPDATE: Paramount Pictures has confirmed that Teenage Mutant Ninja Turtles will not move from its August 8, 2014 release date. Michael Bay also announced on Twitter that the film would not be delayed:
BREAKING NEWS: Megan Fox drops out of Teenage Mutant Ninja Turtles movie due to personal reasons. Apparently one-third of the film is being re-shot for necessary changes to her departure.
No word whether Jonathan Liebesman will return on set but Michael Bay will personally see this through. Our sources have not confirmed Megan Fox's reason for excluding herself from this blockbuster film. Our guess is you fell for our April fools joke.
On a serious note, the film will most likely be delayed until November – December this year. Actors are returning for reshoots to correct the origins and script issues that flared after fans saw the trailer.
