Reagan's Daughter Poses Nude at 58

Reagan offspring Patti Davis, once known as “the rebellious First Daughter,” went from a drug-addicted teen—whose “wasted” body was home to “thin and barely visible” muscle—to a healthy, beautiful woman, she writes in More magazine. The transformation began when she got sober and then started working out at age 34 with the intent of getting strong ... and of someday feeling that she “deserved” to pose nude. That happened first in 1994, when she posed for Playboy at 42—twice the age of the typical Playmate.

She calls that shoot her “victory lap.” Now, at 58, she does it again, in More. This time around, her intent is to prove that exercise works at any age. "I don’t understand the common attitude that after 40, you might as well just accept that your body is going to sag and fold and expand in unflattering ways," she writes. "Our muscles are actually pretty democratic; if we work them, they’ll respond." And in her case, her body is proof that she’s triumphed over her years of addiction. “With every workout,” she writes, “I feel as if I’m winning back lost time.” Read her full essay and see the picture in More.
