Jennifer Lawrence made news in Boston back in February when TMZ reported that she and her “Joy” director, David O. Russell, had an explosive argument on the local set. At the time, Oscar-winner Lawrence took to Facebook to assure people, “David O. Russell is one of my closest friends and we have an amazing collaborative working relationship. I adore this man and he does not deserve this tabloid malarkey.” But in the new issue of Vogue, Lawrence admits that there was fighting on set — and that she started it. “I wasn’t mean to anybody but David,” Lawrence says in the story. “I would never be mean to somebody who couldn’t be mean back. But when you really love somebody, you fight with them. There have been times where I’ve said, ‘We should go to couples therapy.’ ” Lawrence also talks in the December cover story about what it was like to film “Joy” during the winter of 2015, when Boston couldn’t get out from under the snow. “David and I kept saying, ‘Merry Christmas’ to each other to try to make ourselves feel better, but it didn’t work.” “Joy” will be released Dec. 25.
