Gwyneth Paltrow: Actress Promotes Cookbook, Forgets to Take Price Tag off High Heels, Shirtless in 'Iron Man 3' Trailer [VIDEO]

Oscar winning actress Gwyneth Paltrow was turning heads earlier this week when she showed up in a purple dress and orange-strapped high heels to the opening of Tracy Anderson's Brentwood, California fitness studio. The "Iron Man 3" actress; however, forgot to take the price tags off her heels. Paltrow posed for the cameras looking stunning, but did display the one minor price tag gaffe.

Paltrow attended the fitness studio opening with her rocker husband Chris Martin (lead singer of Coldplay) and two kids Apple and Moses. Paltrow was there supporting her business partnership with Tracy Anderson and wasn't the only star in attendance. Among the celebrities at the event were Molly Sims, Stacy Keibler, "Glee" creator Ryan Murphy, and Kim Kardashian. You can check out a photo here of Paltrow at the event, including a photo of the price tagged high heels.

The 40-year-old Hollywood starlet also just admitted that she likes to rap while her rocker hubby is out of the house. She recently told ES Magazine, "But if he isn't at home, I turn on the hip-hop - I'm like a bad mutha rapping along to every word as I cook."

Paltrow is reprising her role as Pepper Potts in the summer movie "Iron Man 3" alongside Robert Downey Jr.. In early video clips and trailers it looks like Paltrow is in the best shape of her life. Paltrow has a new cookbook out titled,"It's All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great." If Paltrow's figure is any indication of how the cookbook works, it should be a huge success. Paltrow is doing a lot of promotion for her various projects. E! Online reports that Paltrow was signing copies of her new cookbook at a L.A. Barnes & Noble this week.
