Model-turned-actress 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 an interview, describing it as "not a movie about acting", reported contactmusic.com.

After the interview, Bay claimed that Fox has "growing to do".

"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," he said.

"Nobody in the world knew about Megan Fox until I found her and put her in Transformers," he added.
