The 24-year-old actress and 37-year-old Coldplay frontman were together for four months, and are said to have split due to their "insane" schedules.
"They really like each other," an insider told Us Weekly. "But it's just so complicated with so much going on."
Lawrence and Martin started dating shortly after the actress broke up with boyfriend Nicholas Hoult. She attended Martin's performance at the iHeartRadio music festival September 19, and the pair were photographed together as they deplaned September 20.
Lawrence will next appear in The Hunger Games: Mockingjay - Part 1 in November, and is scheduled for The Hunger Games: Mockingjay - Part 2, David O. Russell film Joy and X-Men: Apocalypse.
