Madame Tussauds in New York has rejected claims of "whitewashing" over its latest Beyonce waxwork.
Visitors have criticised the likeness of the model, saying it does not resemble the singer and some claimed her skin had been lightened.
The backlash over the figure, which was unveiled earlier this month, has prompted Madame Tussauds to issue a statement defending the sculpture.
It said that lighting and flash photography can sometimes distort the image.
"Our talented team of sculptors takes every effort to ensure we accurately colour match all of our wax figures to the celebrity being depicted," the company told TMZ.
"Lighting within the attraction combined with flash photography may distort and misrepresent the colour of our wax figures," it added.
One Twitter user wrote: "Who made that God awful beyonce waxwork and WHITEWASHED her?!"
Another tweeted: "it's a good thing you're not talking about *Beyoncé. cause this white woman is definitely not her."
Others said the artwork looked more like Lindsay Lohan or Shakira.
One fan said: "That new Beyonce waxwork looks nothing like Beyonce".
Beyonce recently gave birth to twins Sir Carter and Rumi. The singer posted an elaborate photograph of her with them on Instagram.
