Megan Fox has revealed getting the hourglass figure for Western drama Jonah Hex was painful.
The Transformers star trimmed her waistline to a mere 18 inches for the part of Lilah, which she managed with a super-tight corset.
Comparing it to wiggling a loose tooth as a child, 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."
Megan gets to work with Josh Brolin in Jonah Hex, based on the graphic novel of the same name.
"He's very witty and charismatic, and so talented. He's very likeable so it wasn't hard to have chemistry," she revealed.
