According to E! News, the Oscar-winning actress and the Coldplay frontman have decided to put an end to their relationship.
Earlier this month, Jennifer was seen at the Hollywood Bowl supporting and cheering Chris when he performed with Kings of Leon, but also at the iHeart Radio Music Festival.
The two have been very discreet about their relationship and were only photographed together once while stepping off a private jet.
Lawrence, 24, began dating Martin, 37, last June, shortly after her breakup with her boyfriend Nicholas Hoult.
For its part, the Coldplay rocker announced his separation from Gwyneth Paltrow a few months earlier.
