Lawrence, 24, has been increasingly busy as of late with her multiple movie projects. With her focus on her career, there hasn’t been much time for her relationship with Martin.

“Jen has been working nonstop and they never saw each other,” an insider told Us Weekly, confirming the breakup. According to the source, the romance once again “ran its course.”

Lawrence and Martin, 38, were dating for about four months before parting ways last November. The two reconciled in December, but have once again decided to break up.

Newly single, Lawrence is reportedly growing close to her ex-boyfriend and X-Men costar Nicholas Hoult. “They’re on great terms now,” the source added. “And their families have stayed close.”

While Lawrence might be rekindling things with Mad Max star Hoult, Martin has sparked romance rumors with his longtime pal Kylie Minogue. Gwyneth Paltrow‘s ex-husband was recently spotted strolling the streets of London at 1 a.m. with the singer after one of her concerts.

Neither Lawrence nor Martin have commented on their relationship or apparent split.
