Lisa Rinna is most comfortable in the nude, which may explain why the 45-year-old doesn’t understand why there is so much stigma attached to not having a perfect body.

“While I’m definitely a product of this mindset, I don’t get all the fuss our society has over people’s weight,” actress Lisa Rinna told PEOPLE Tuesday night during Kate Somerville’s skin care launch at the Four Seasons Resort in Palm Beach. “I am more comfortable being nude than hosting an event like this.”

Added Rinna, who is set to pose nude on the cover of Playboy‘s May issue: “It is best to be moderate. I focus on fitness, eat healthy, and am lucky that I am not anorexic and my weight stays the same.”

In fact, the actress believes she looks better now than she did at 34 when she posed for Playboy while pregnant.

“I want to encourage other women to be proud of their bodies no matter what age or size,” said Rinna, looking toned in a short floral, bejeweled Bluemarine dress. “After doing Dancing with the Stars, I definitely have a better body now than I did 11 years ago.”

Her husband and frequent on-screen costar, Harry Hamlin, heartily agrees.

“Lisa looks absolutely great, and I am happy other people will be able to see her on the cover of Playboy,” Hamlin, 58, told PEOPLE. “Some guys like having people see their wife naked, others do not. But I can tell you that while these artful photos of Lisa will blow you away, if someone asked me to pose nude I would run the other way.”
