LONDON: Megan Fox will never be caught out by a leaked sex tape - because she would hate to see herself looking like a "hippo" during filmed romps.

The sexy Transformers actress is lusted after by millions of male fans around the world, and regularly tops sexiest woman polls.

But fans will be waiting a long time if they want to see the star's bedroom technique - because she would never film herself having sex.

She tells MTV.com, "Ugh, never! 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."

And Fox insists she wouldn't even strip off for a film role - because fans already have too much of an insight into her personal life.

She adds, "I can't ever imagine myself doing nudity in a film. It lives forever, especially now, with the internet. I just can't. I just can't."

"People take everything from you when you're in this business. Your anonymity is stripped from you. They invade every part of your personal life, your relationships. Everything you say gets judged, everything you do gets judged.

"Literally all I have left are my private parts and I don't want to also share them with the world. I'd like to keep them private. That's why they're called that!"
