Reports in the USA say the couple were introduced by Lawrence's friend Laura Simpson.
According to People, the 33-year-old Maroney is part of New York's art scene and is a director at Gladstone 64, a gallery on Manhattan's Upper East Side.More news: Ladies and gents, these are your new Emoji for 2019

Could Jennifer Lawrence be taking the next step in her relationship and heading to the altar?!
We're starting to think we never knew Jen at all after learning that not only has she been going out with someone for a good while but that she's actually getting married. Another source told Harper's Bazaar they'd seen J-Law wearing "a giant rock" on her wedding ring finger. One of the gallery's biggest clients is Lena Dunham's artist father, Carroll Dunham, who has shown his work there.
Jennifer took Cooke to the NY premiere of The Favorite in September, when the new couple rubbed shoulders with her pal Emma Stone and exes Darren Aronofsky and Nicholas Hoult, who appears in the film.
Lawrence and Aronofsky ended their one-year relationship in October 2017.
