Heidi Montag Asked Kim Kardashian For Playboy Advice

'I talked her through the whole process and helped her make up her mind,' Kardashian says of 'Hills' star.

Although "Hills" star Heidi Montag played coy on Monday when MTV News asked about her reported pictorial for the September issue of Playboy, her friend Kim Kardashian talked freely about Heidi's photos, which, according to Spencer Pratt, are "hypothetically" set to hit newsstands in August.

In fact, it was Kardashian, who has posed for Playboy herself, who helped the "Hills" star make the decision to pose for the magazine.

"Actually, I was in Mexico and I got a call from Heidi saying, 'Call me right now,' " Kardashian told MTV News on Tuesday (June 16). "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?' "

Kardashian told her to "go for it."

"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."

Of course, Kardashian, who is currently the spokeswoman for Nivea's "Good-bye Cellulite, Hello Bikini" challenge, wasn't the only person who helped Heidi make up her mind. Spencer also had a hand in the decision-making process. "Her and Spencer talked it over," Kardashian said. "They felt like it was the right thing for her to do and I'm anxious to see it."

Kardashian is confident that Heidi had as good an experience as she did when she posed for the magazine.

"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."
