Megan Fox has been dubbed "ridiculous" by her Transformers 2 director Michael Bay, after she slammed the movie in an interview.

Fox took a swipe at the sequel in a new interview, describing it as "not a movie about acting".

She told Entertainment Weekly, "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**. People are well aware that this is not a movie about acting."

Bay has laughed off the comments, but claims Fox "has growing to do".

He says, "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."

Bay also boasts his movies have long been stepping stones for actors on their way up: "Nic 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."
