Jennifer Lawrence calls reports of rift with director David O. Russell 'malarkey'

LOS ANGELES, Feb. 28 (UPI) -- Jennifer Lawrence is denying media reports that claim she and director David O. Russell have been fighting on the set of their third collaboration, Joy.

"It's Jen! I know I don't go on here a lot because I can barely work email but there's been a terrible rumor going around the last 24 hours so I wanted to clear it up," Lawrence posted on Facebook Friday. "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. This movie is going great and I'm having a blast making it!"

Lawrence won an Oscar for her performance in Russell's Silver Linings Playbook. She earned an additional nod for her work in the filmmaker's American Hustle.
