Gwyneth Paltrow and Chris Martin’s amicable post-divorce relationship set the blueprint for how to maintain a friendship even after the romance fizzles out.The Goop founder met Martin in 2002 while his band, Coldplay, was on tour in Los Angeles. In April 2013, Paltrow recalled their unconventional introduction.“It’s funny because people had started writing that we were going out and we had never even met,” she said during her Iron Man 3 press tour.
