Megan Fox has vowed never to make a sex tape.
Actress Megan Fox, star of "Transformers: Revenge of the Fallen", poses at the film's premiere in Los Angeles, California June 22, 2009.
The "Transformers: Revenge of the Fallen" actress is convinced if she saw herself having sex and "looking like a hippo" it'd put her off making love for the rest of her life.
She said: "That's the last thing I want to see - what I look like having sex. It would take one shot of me not looking good and I would not be able to have sex ever again, because I would always just see myself looking like a hippo having sex."
For much the same reason, Megan, 23, has also vowed never to appear naked on screen in any of her films, and is still mortified by photos of her in a flesh-coloured suit on the set of forthcoming cheerleader-turned-killer film "Jennifer's Body".
She added to MTV: "I can't ever imagine myself doing nudity in a film. It lives forever, especially now, within the Internet. I just can't.
