Patti Davis, the daughter of late U.S. president Ronald Reagan, has posed nude for More magazine at the age of 58.
"My body is the house I live in, and I've never stopped trying to make it better," Davis wrote in More. "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. Really? Our muscles are actually pretty democratic; if we work them, they'll respond."
The writer, who was often considered the "black sheep" of the Reagan family, also posed nude for Playboy magazine in 1994 when she was 42. The more liberal Davis became a drug addict when she was 15 and told More magazine that she is finally proud of her body.
Davis tried acting briefly, appearing in episodes of "Fantasy Island," "CHiPs" and "The Love Boat." She was romantically linked to the Eagles member Bernie Leadon and was married to her yoga instructor for four years.
During Reagan's presidential run, Davis vocally opposed nuclear weapons and supported the pro-choice movement. Davis wrote an autobiography "The Way I See It," where she accused her mother of physical abuse and called her father distant and aloof.
She eventually reconciled with her parents and wrote "The Long Goodbye," a memoir about losing her father to Alzheimer's disease. In total, Davis has written eight books and numerous articles.
