Megan Fox doesn't rate her own acting.

The 'Jonah Hex' actress - who is engaged to actor Brian Austin Green - insists she would never complain about receiving more attention for her looks than her work as she has not yet given "any reason" to win praise for her movies.

She said: "I'm totally aware that I've never given anyone a reason to praise me for my acting talents.

"So to sit here and complain, 'Why don't people recognise me as an actress?' would be outrageous.

"It's my responsibility to prove that they should."

The brunette beauty also admitted she rarely reads anything about herself as she fears it would turn her into a "drug-addled lunatic".

She added to Sky Movies magazine: "I could never be one of those actors who reads everything that is ever written about them.

"That doesn't work with my personality. I'd be a complete lunatic, probably drug-addled and out of my mind. Instead, I stay in and ignore it."
