Kim Kardashian vows never to pose naked for Playboy again?

Kim Kardashian has vowed never to pose naked for Playboy again.

The 28-year-old beauty - who appeared as a Playboy Centerfold in the pages of the adult publication last year - has no plans to strip off again in the future.

She said: "It was a one-off. I don't think I'll do Playboy or anything like that again."

Kim - who is dating American football player Reggie Bush - also revealed she likes to think of herself as Reggie's "lucky charm".

She added: "I don't have to sneak into games. I'd like to think I was his good luck charm, but I'd also like to think he plays at his best even when I'm not there."

Although Kim is finished with Playboy, Mel B is keen to bare all in the explicit magazine.

The former Spice Girl recently revealed she had turned down two offers to appear in the publication but is starting to warm to the idea.

She said: "I was offered Playboy last year and again a couple of months ago, and I did turn them down, but that's not to say I wouldn't consider it in the future. I have no problems walking around the house naked or anything."
