Actress Gwyneth Paltrow is catching some flak by promoting a new bikini line for girls as young as 4 years old.

Paltrow's website shows a photo of an ad, which says the design is perfect for girls who want to match their mothers.

Critics say the bikini sexualizes children, but a spokesman for Paltrow says the criticism is absurd.

The bikini sells for about $40.
