Jennifer Lawrence is ''seeing what happens'' with her ex-boyfriend Darren Aronofsky.

The 27-year-old actress started dating the 48-year-old filmmaker while starring in his latest psychological thriller 'Mother!', but their relationship was short-lived as they decided to call it quits just two months ago following a year of romancing.

However, tongues starting wagging on Wednesday (20.12.17) when the pair were spotted walking into a house together in New York City.

A source told E! News: ''They never stopped speaking after they broke up. They care about each other. They are just seeing what happens.''

The pair never addressed the reason why they broke up but it's believed their 21-year age gap may have played a role in their decision to go their separate ways.

The insider said: ''Once they are onto new projects and interests, it's harder to keep up relationships of any kind. They were never destined for marriage. They had fun, shared many beliefs, and enjoyed what they could learn from each other.

''There is a huge age difference, and they are different people. Each has to look practically to the future. Jen has yet to figure out her life and how it will evolve. He has responsibilities in life that she has yet to experience.''

The 'Passengers' star recently admitted the movie drove them apart, as whilst she would be sick of talking about the feature, he would keep pressing the subject.

She said: ''We'd be on the tour together, I'd come back to the hotel and the last thing I want to talk about or think about is the movie, and he comes back and that's all he wants to talk about.

''I was doing double duty of trying to be a supportive partner while also being like, 'Can I please, for the love of God, not think about 'Mother!' for one second?'''
