Megan Fox needs to grow up, says her 'Transformers' director.

The 23-year-old actress recently slammed Michael Bay for focusing more on  special effects than acting in the 2007 blockbuster but Michael says her  comments are "ridiculous" and should be ignored.

Michael - who recast Megan in this summer's sequel 'Transformers: Revenge of  the Fallen' - said: "Well, that's Megan Fox for you. She says some very  ridiculous things because she's 23 years old and she still has a lot of  growing to do.

"You roll your eyes when you see statements like that and think, 'OK Megan,  you can do whatever you want. I got it.' "

Michael thinks Megan should also show more gratitude towards him for helping  to launch her movie career.

He added to Us Weekly magazine: "Nick Cage wasn't a big actor when I cast  him, nor was Ben Affleck before I put him in 'Armageddon'. Shia LaBeouf  wasn't a big movie star before he did 'Transformers' - and then he exploded.  Not to mention Will Smith and Martin Lawrence, from 'Bad Boys'.

"Nobody in the world knew about Megan Fox until I found her and put her in  'Transformers'. I like to think that I've had some luck in building actors'  careers with my films."

Talking about her role in 'Transformers' Megan previously said: "I mean, I  can't s**t on this movie because it did give me a career and open all these  doors for me. But I don't want to blow smoke up people's a*s. People are  well aware that this is not a movie about acting."
