Ever since the separation -- oh, sorry, I mean "conscious uncoupling" -- of Coldplay's Chris Martin and actress Gwyneth Paltrow, rumors have been circulating about why, exactly, the duo separated. And People Magazine -- amongst others -- have the answer: because the duo had an open marriage!

According to The Huffington Post, the couple's marriage -- which produced a son, Moses, and a daughter, Apple -- was over for a long time before they officially split. "If Chris was playing around, Gwyneth didn't care. She's never been jealous or territorial. Her philosophy is, 'We're both adults. We make our own choices,'" reports the site, which is pretty noble considering that Gwyneth felt entitled to cheat on Brad Pitt while she was dating him.

Of course, Gwyneth wasn't exactly innocent throughout their marriage, either: she reportedly had several flings, including with billionaire Jeff Sofer, entertainment attorney Kevin Yorn, and even rapper Jay-Z!

"They have been on and off for many years. The marriage was falling apart," continues the site. "It caused both of them tremendous pain, and they tried to fix it day after day."

Still, according to Us Weekly, it wasn't just the famous flings that got the couple arguing: reportedly, the couple fought about everything, from Gwyneth's ridiculous diet restrictions, to where their "home base" would be (Gwyneth wanted Los Angeles, Chris wanted London). In addition, Gwyneth reportedly always made fun of what Chris ate, and frequently mocked him to her family and friends.

In October 2002, Paltrow met Chris Martin backstage three weeks after the death of her father, Bruce Paltrow. They married on December 5, 2003, in a ceremony at a hotel in Southern California. Paltrow's father came from a long line of influential Eastern European rabbis, and that inspired Paltrow to raise her daughter and son in a Jewish environment. Paltrow cut down on work after becoming a mother. In March 2014, Paltrow announced that she and Martin had separated after ten years of marriage, describing the process as "conscious uncoupling".
