The "Hunger Games" star has been spending more time with her ex-boyfriend Nicholas Hoult as they are filming "X-Men: Apocalypse" together, reported Ace Showbiz.
"Jen has been working nonstop and they never saw each other," a source said, adding, "They're (Jennifer and Nicholas) on great terms now. And their families have stayed close."
Back in May, Lawrence, 24, was seen smiling widely while posing for a selfie with Hoult and Bryan Singer.
News of the actress and Martin's break-up comes more than a week after the Coldplay frontman was rumored to be dating Kylie Minogue.
