Jennifer Aniston and Gerard Butler cover 'W' magazine in the walk-up to the release of their movie 'The Bounty Hunter,' out March 19.
The spread was shot at a ranch outside LA by Steven Klein, he who shot Brad and Angelina's infamous 'domestic bliss' pictorial for the magazine in 2005. It's called "Speed Trap: Jennifer Aniston and Gerard Butler do a little role playing in the searing heat of the California desert where damsels aren't always in distress and lawmen sometimes break the rules."
Jen's hair stylist, Chris McMillan, told the magazine he left her hair dirty for the shoot.
"It just created a nice chunky texture," he said. "The key to Jennifer's hair is no matter what you do with it -- straight, frizzy, dirty -- it looks like it actually grows out of her head. She's someone for whom her hair doesn't wear her, she wears it."
McMillan also takes a preemptive strike against criticism.
"They're going to be talking s**t as usual, but who cares? We don't care about that."
