The actresses' genitals and breasts are carefully covered in the shots, which were tastefully snapped by MICHAEL THOMPSON for a celebrity female beauty special.
Sedgwick, who has never posed naked in front of anyone except her husband Kevin Bacon, loved the shots Thompson took of her.
She says, "My husband will like these. They're perfectly wallet-sized."
Meanwhile, De Matteo, who plays the recently-killed ADRIANA in The Sopranos, admits she has no problems with nudity - although she's glad the photoshoot didn't take place at the beginning of her hit show's season.
She explains, "Every season I've gotten more used to playing Adriana. I show up to work 20 pounds overweight."
And Anne Heche was delighted the shoot would give her something impressive to show her son HOMER when he grows up.
She says, "My son's going to see this one day and be like, 'That's my mom's a** in Allure.'"
