Los Angeles - Jennifer Aniston was "bizarrely comfortable" with the sexy scenes in Horrible Bosses.
The 42-year-old actress - who plays a sexually ferocious dentist who preys on her colleague in the comedy - quickly had to be undressed in front of co-star Charlie Day just minutes after they met, but found she didn't mind.
Lingerie
She said: "I've never been on a set like this - within 20 minutes, I was straddling him in lingerie, I was bizarrely comfortable in these scenes, almost more than I would be playing the normal girl-next-door, and every scene was kind of crazy but that was really the fun of it."
Jennifer - who is currently dating actor Justin Theroux, and has previously been in relationships with Vince Vaughn, John Mayer and Paul Sculfor - was particularly keen to work on the movie, which also stars Colin Farrell and Kevin Spacey, because it was a role reversal from normal Hollywood films.
She said: "That's what I think was so fun about it, sort of being a female that's usually the male character. I thought of her as kind of like a guy and that made it that much more fun."
