(Do we detect a trend here?)
"When I was asked to do it, I didn't realize I was actually going to be stripping off naked," the 44-year-old mother of four says in a video interview with Grazia.
"The whole issue for me, the reason I wanted to do it, was because I wanted to put such emphasis on being healthy and holistic. And I felt that there's been so much pressure on women, and I've noticed such a negative movement over the last few years on how peoples' bodies should be.
"Really, I just think it's sending out the wrong message to women. So I thought it would be really good, and that's what I talked to everyone at Grazia [about] and they've been incredibly supportive with doing something that was much more realistic.
"So there's no airbrushing; what you see is what you get, and I just wanted to give people some idea about healthier options and not to be too extreme or too punishing, and be a bit kinder to ourselves and maybe be a bit more sisterly, and that's what I enjoyed talking about doing."
So is going unairbrushed the new black? Looks like it. Now let's see who's brave enough to drop trou next!
