Chloe Grace Moretz has said she has no interest in dating a co-star - because it can ruin a movie.

The 16-year-old, who stars in Carrie, admitted she has seen first-hand what failed romances can do to a film.

"I grew up from the age of five on a set, so I've seen co-star relationships ruin a movie," she said.

"I have seen an actor get with an actress and they break up halfway through - they have to be in love during the movie and they can't even touch each other. So I've learnt this is what not to do."

Having to deal with egotistical stars isn't something she is particularly keen on either.

"I don't like actors! There's a lot of ego to deal with and I can't do that. It's like dating a girl - they probably have extensions in their head, make-up on their face, and they care about the shape of their beard more than what my hair looks like," she added.

Chloe also revealed that the perceptions surrounding child actors can be frustrating, but she doesn't plan to fall into the same traps as troubled former child stars like Lindsay Lohan and Amanda Bynes.

"A lot of people my age expect me to be pretentious, and [for it to be] thrown in their faces that I'm an actor," she said.

"And a lot of parents, especially when I'm with a guy, expect their son to be run to the ground because I'm going to be partying and they don't condone it - until they meet me. Then they're like, 'You're normal', and I think, 'Respect! Not everyone's a coke addict and in rehab at 12!', but that's how it's perceived."

:: Carrie opens in cinemas on November 29.
