Sexy Toni Braxton is in negotiations to appear naked in men's magazine Playboy - as long as she doesn't have to show off her genitals.

The 37-year-old UNBREAK MY HEART singer insists she has no problems baring her boobs in the publication, but refuses to show her nether regions.

She says, "I just can't do the bottom thing because that's really, really intimate and really personal.

"But boobies, what is it? A dime a dozen. You can buy some for $5,000. Who cares? But the thing down there, you can't really buy that."
