Gwyneth Paltrow Unfazed with ‘Iron Man 3’ Action Scenes and Criticisms on Selling Bikinis for Kids [PHOTOS]

Actress Gwyneth Paltrow reprises her role as Pepper Potts in "Iron Man 3" and admitted she was unfazed with the action scenes in the blockbuster film that will hit cinemas on April 25. The 40-year-old Hollywood star revealed she did not have any training because her workout regime is already intense and strict.

"I work out all the time and my trainer is really strict with me and I'm very disciplined about it. I was prepared," Paltrow stated about her role in the film. Gwyneth Paltrow further revealed that working with Robert Downey Jr., who portrays Tony Stark/Iron Man, was challenging for her because the actor always improvises on the banter scenes of their film characters.

According to the Oscar-winning actress, she enjoyed Pepper Pott's involvement in the latest film's action scenes. "This one was really fun because I felt like Pepper really progresses. She really steps into her power this time. She gets involved in all sorts of action so this one was the most fun in terms of where she is in her life," the actress shared.

Gwyneth Paltrow is being slammed for selling bikinis for kids aged 4 to 8 on her "goop.com" web site but the actress appears to be unfazed as well. The actress' spokesman stated that the criticism is "absurd" since two-piece bathing suits for young girls have been around for decades.

Gwyneth's collaborative work with designer Melissa Odabash enraged the child abuse campaigners because they believe the bikinis sexualize the young girls. Claude Knight, a representative of "Kidscape" which is a British foundation set up to prevent child abuse, told the Daily Mail that they are very opposed to the "sexualization" of children and childhood.

""The dangers have been discussed at length so it is a great pity that such trends continue and that they carry celebrity endorsement," Knight stated. The kids' two-piece bikini limited edition is exclusively offered at Gwyneth Paltrow's web site at a price of $45. The item has been described as the "perfect way for kids to have their own version of mum's bikini."
