The Oscar winner, 28, sparked engagement rumours when she was spotted wearing a “massive ring” while enjoying a night out with Maroney, 34, in New York at the weekend, according to the New York Post’s Page Six.
A source quoted by Harpers Bazaar said Lawrence wore “a giant rock” to the date at French restaurant Raoul’s.
“They seemed like they were celebrating and people were talking about it,” the insider added. “The ring was very noticeable. They were sitting back in a corner.”
Lawrence was first romantically linked to art dealer Maroney in June 2018, and the pair have since been pictured together numerous times.
According to reports in the US, they were introduced by Lawrence’s friend Laura Simpson.
Lawrence is known for starring in films such as Hunger Games and 2012’s Silver Linings Playbook, for which she won the best actress Oscar.
She has previously dated Coldplay front man Chris Martin, actor Nicholas Hoult and director Darren Aronofsky.
A spokesperson for Ms Lawrence confirmed the engagement today. No wedding date has as yet been announced.
