Curvy singer-actress Jennifer Lopez demanded museum bosses in London make her Madame Tussaud's waxwork more slimline. The sexy star was reportedly unhappy with the famous museum's newly installed model of her -- particularly their interpretation of her trademark bottom.

So Lopez, who often boasted how proud she is of her voluptuous derriere, asked Tussaud's to shave 10 pounds of wax off her behind.

A museum source tells Britain's the Daily Star, "We always show artists and managers the final waxwork of themselves.

"It's only fair -- but with J.Lo, she wasn't too pleased.

"She suggested we'd gone a bit off on her behind, so we offered to rake some away.

"All in all she wanted about 10 pounds to be taken off, [and] naturally we meet the star's wishes." [link]
