The two began seeing each other in September shortly after wrapping mother!,which Aronofskymdirected,and their relationship continued to blossom despite their 22-year age difference. The private couple kept mum about their relationship while promoting the movie a year later and only posed together at the New York premiere of the film.


The Oscar winner was first spotted dining with the Brooklyn native in New York City in August. They then spent time in Los Angeles in October, where they had an intimate dinner with her close friends at the Commissary restaurant at The Line Hotel.

Lawrence was previously linked to British actor Nicholas Hoult and Coldplay frontman Chris Martin.


Aronofsky has called Lawrence a "once-in-a-generation talent...a whirlwind and a hurricane and an earthquake and a thunderstorm of talent." It's unclear why the pair split, but clearly they still admire each other no matter what may have happened.
