Megan Fox has claimed she isn't as famous as Jennifer Aniston or Britney Spears.

The Transformers star made the observation in an interview with Entertainment Tonight about how she deals with her celebrity.

"I see some people who have to deal with it on an everyday basis - I am not a Jennifer Aniston or a Britney Spears or even a Lindsay Lohan, you know?" she said.

"My pictures don't sell for that kind of money."

Fox, who is currently starring in the Transformers sequel, Revenge Of The Fallen, also revealed that she hasn't yet become comfortable with the attention she's received following the first movie.

"I definitely feel ill-prepared. I mean, I don't know if anyone ever sits back and goes, 'Now is the moment that I think I should be a famous celebrity',” she said.

"I know I'm struggling with trying to figure out how to live in it, but I definitely feel it's premature. I mean, I was in one movie that people have seen.”

But Fox added that she had now reached the stage where she occasionally had to ask someone to do her shopping for her.
