While Cameron Diaz and Megan Fox have starred in upcoming horror films, both of them are petrified of watching spooky movies.

In fact, Diaz has said that even the previews of scary flicks can freak her out. "You know what terrifies me? Trailers to horror movies! I just can’t watch them.

I hate horror movies. I’m always afraid," People magazine quoted Diaz as saying while previewing her psychological thriller.

And the actress said that she especially could not watch them at night. "I kind of want to look, but I’m always.

Afraid that I’m going to look too long and see the one image that I’m not going to be able to get out of my head for at least a week every night before.

I’m going to bed," she added with a shudder.  Meanwhile, Fox, who stars in the sexy-gory scare-fest ‘Jennifer’s Body’, just avoids them altogether.
