Actress Liv Tyler has discovered a new way of losing weight - starring in a horror film.
The 'Lord of The Rings' beauty reveals she dropped "about 10 pounds" while making new film 'The Strangers' - because she had to run around, acting terrified throughout the shoot.
Now she recommends the odd weight-loss programme to other actresses who are trying to shed the pounds.
She says: "We had to be in that heightened state all the time and when you get scared or you're shocked you kinda have a hard time breathing and you're like hyperventilating and crying and screaming.
"It was a great diet. I actually lost about 10 pounds in two weeks because I was running all day. It was amazing.
"I was like, 'Jeez, I need to do this more often.'"
