Jennifer Aniston forces herself to endure a gruelling diet regime - because she wouldn't be able to find work if she gained weight.

The former Friends star admits she loves junk food, but has to watch what she eats in order to maintain a super-svelte figure.

She tells Elle magazine, "I'm a realist. I know that if I eat nothing but burgers and chips, I'm not going to be hired for the parts I normally would. That might be fine one day, but not right now."
