Kim Advised Heidi on Playboy

It seems Playboy should thank Kim Kardashian for convincing Heidi Montag to appear on their pages in the September issue. The reality TV vet says she advised her fellow reality star to "go for it."

"Actually, I was in Mexico and I got a call from Heidi saying, 'Call me right now,'" Kim tells MTV News on Tuesday. "So I called her and she had said to me, 'What do you think? What's your opinion on if I were to do Playboy?' "

Kim, who graced the men's mag in 2007, gave her the thumbs up.

"I think that now's the time," she said. "I think it's a very classy magazine. It's artsy. I talked her through the whole process and helped her make up her mind."

Obviously the decision wasn't made solely by the two reality ladies, as Heidi's hubby Spencer Pratt took some time from grooming his immaculate blond beard to throw his two cents in.

"She and Spencer talked it over," Kim reveals. "They felt like it was the right thing for her to do and I'm anxious to see it."

Obviously Kim is hoping Heidi will have as much fun as she did when she bared it all (almost) for Playboy.

"It was a really fun process for me," she said, adding that getting asked to be on the cover is an "honor." "I'm excited to see what the pictures will turn out to be."
