Former Law & Order star Angie Harmon is still struggling to believe she bared all for a magazine - because she's such a prude in real life.

The actress joined Gabrielle Union, Ana Ortiz and singer Jill Scott for Allure magazine's annual naked spread, and she admits she had more problems disrobing than her fellow celebrities.

Harmon says, "The hardest part was when the robe came off and I was like, 'And now I'm... naked.' You wonder if they can see your Caesarian scar."

Harmon also reveals she has skinny-dipping photos she took on holiday with her husband that she can't bear to get developed because she fears what photo lab assistants will see.

She explains, "We were on a private beach in Bora Bora and we took one picture of our heads under the water, but we can never develop the film because we don't know what else is showing."

Union, Harmon's fellow 'stripper' for the tasteful new spread, admits she worked hard to make sure she looked great for the photo session.

She explains, "I've always been athletic, but I stepped it up for this. I ran up and down stadium stairs and went hiking. I'm cool with being naked, but I wanted to push myself." (c) WENN
