Lisa Rinna was ordered to stop working out before her new Playboy photo shoot.

I'll admit that I find her very attractive. I know, I know... those lips any plastic surgery aside, I think she's amazing. 45? Nice! Yeeah has the photos. Obviously NSFW.

How did Lisa Rinna prep for her May issue of Playboy?

By not working out.

Rinna, 45, tells that photographer Deborah Anderson gave her the specific order.

"She knows that I'm a workout fiend and she said, 'Lisa, I don't want you to work out, and I don't want you to starve yourself before the shoot, because I know you will,'" Rinna tells Us.

When she agreed to bare all, Rinna says she thought, "'OK, I've really got to limit my food intake and be really good. I've got to workout everyday, twice a day, like crazy.'"

But Anderson told her she didn't want her "muscular, hard, sinewy." She needed to look "soft and beautiful," Rinna recalls.

Says the star, "At first I was like, 'Oh, forget it!' But then I listened to her and said, 'You know what? I've got to trust her. She's an amazing photographer.'"

It wasn't easy.

"I had to really remind myself every time, and go, 'It's OK to eat!'" Rinna tells Us. "She would email me constantly, 'Are you starving yourself?' and I would email back, 'No.'"

Rinna tells Us she stopped working out "for three weeks, which is unheard of for me because I'm a fiend."

In the end, Rinna says, "I felt great -- and I looked great! I'm really pleased with how my body looked in Playboy."
