and Nicholas Hoult's 'difficult schedules' have reportedly taken a toll on their relationship as the couple have reportedly split up again.
The couple, who are also co-stars on X-Men: Days of Future Past, briefly split last year, reported Us magazine.
Heavy workload reportedly contributed to
and the British actor's 2013 split and it apparently is still the reason of their recent break up.
"They just weren't together a lot, her life is a whirlwind. They have gotten back together before, it just got to be too hard for now," a source said.
Earlier this year, the 23-year-old Oscar-winning actor talked about her relationship with Hoult in an interview, sharing how she and her boyfriend juggled work and personal life.
Lawrence and Hoult were last photographed together in May.
The 24-year-old actor, meanwhile, was most recently seen having a meal with Kristen Stewart. The two, who will play lovers in Equals, were seen by a fan at Tsukiji Market, Tokyo.
