OTRC: Gwyneth Paltrow has a fashion faux pas, defends Kim Kardashian (Photos)

Want to know how much Gwyneth Paltrow's shoes cost? You might just have to look at the soles of her fashionable heels.

The Oscar-winning actress suffered a bit of a fashion faux pas at a recent red carpet event to celebrate the opening of the flagship workout studio by trainer Tracy Anderson. It appears Paltrow left the price tags to her shoes on the bottom of her heels.

Paltrow was wearing ankle-strap shoes by Michael Kors and a dress by Victoria Beckham at the event on Thursday, April 4. According to The Huffington Post, the stickers appear to be "barcode labels that PR companies use to track samples lent for photo shoots and celebrity appearances."

The shoes can be seen in the photo above. While attending the event, Paltrow was also asked about the criticism Kim Kardashian has gotten over the weight she has gained during her pregnancy. Kardashian also attended the event and is Anderson's client.

"I think that women should support each other, especially through pregnancy," Paltrow told ET Online on Thursday. "It's a difficult time and I think Kim Kardashian looks absolutely beautiful. And we're supposed to gain weight when pregnant -- that's how God intended it."

Paltrow's new cookbook titled "It's All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great" was released on Tuesday, April 2.
