MEL B REJECTS $1.8 MILLION PLAYBOY OFFER: Singer says nudie show is for her husband's eyes only

Melanie "Scary Spice" Brown says she has turned down a $1.85 million offer from Playboy to pose in the buff because that vision is strictly reserved for her husband.

"I'm not going to do it," she tells Access Hollywood, adding that she'd prefers to show off her birthday suit to her husband Stephen Belafonte in the privacy of their own home.

She said: "There is (an exhibitionist side to me) - in my bedroom, late at night for hours on end!"

The former Spice Girl does strip down to her lacy underwear as the spokesmodel for underwear company Ultimo.
