Gwyneth Paltrow has vowed to return to the U.K. before her kids grow into teenagers. The actress and her husband, Coldplay rocker Chris Martin, have moved the family from London to Los Angeles to give them experience of living in Paltrow's native America. But the star is adamant she will return to her U.K. home within three years as she doesn't want Apple, nine, and seven-year-old Moses to be teens in Hollywood. She tells Red magazine, "I don't want my children to be teenagers in LA. No way. I'm looking at this move to America like two years, three years tops - then we will go back. "It's part of my parenting philosophy that children should get the opportunity to reinvent themselves at a few points in their childhood to see where their strengths and weaknesses lie and to experience living in different cultures. It's an experiment. "I love London - it's my favourite city in the world. I love my house and my life there. But in California, I have the girls I grew up with and my family."
