Megan Fox has revealed that the corset she wore in new movie Jonah hex hurt.
It seemed that the actress suffered for her art in her new movie, which sees her star alongside Josh Brolin, John Malkovich and Michael Fassbender, as she got her waistline down to just eighteen inches.
She told Entertainment Tonight: "It hurt, but you can't resist wanting to mess with it - I was obsessed with getting it as tight as we possibly could and, in a lot of the scenes, we got it down really small."
Jonah Hex is superhero Western film based on the DC Comics and sees Jimmy Hayward, who brought us Robots and Horton Hears A Who!, in the director's chair.
Fox takes on the role of gun wielding prostitute Leilah in the movie, as well as Jonah's love interest, and Fox had nothing but praise for her co-star Brolin.
"He's very witty and charismatic, and so talented. He's very likeable so it wasn't hard to have chemistry," she revealed.
Jonah Hex is the first movie of 2010 for Fox but she will be back later this year with Passion Play alongside Mickey Rourke.
