The three women all pose with bare faces for photographer Juergen Teller in his shoot for W magazine.
Twilight star Stewart is seen sporting heavy bags under her eyes and seemingly unwashed hair in her picture, while Cotillard, who is wearing just a towel, looks fresh-faced having just stepped out of the shower.
Kidman and her longtime friend Naomi Watts also posed without make-up for the shoot, and in the accompanying interview, the King Kong star insists she is rarely recognised in public when she sports a casual look.
She says, "I never get recognised on the street. I'm lucky that way. People see me as the dolled-up movie-star type on the red carpet, but in real life, I don't look anything like that. I blend easily into a crowd. My husband (sic), Liev Schreiber, is really distinct, and quite often people push me aside to get to him... They will then ask, 'Can you take a photo of us?' They have no idea who I am."
Male stars who went without air-brushing for the spread include Matthew McConaughey, who showed off a skeletal frame after slimming down to play an AIDS victim in new movie Dallas Buyers Club.
Daniel Day-Lewis posed in a casual outfit of a knitted sweater and jeans, Jarvier Bardem wore just a blanket and Philip Seymour Hoffman was seen wearing a beanie hat, dirty trousers and a weather-proof jacket.
Other stars featured in the shoot include Jack Black, Jessica Chastain and Keira Knightley.
