Jennifer Lawrence has given Darren Aronofsky keys to her home.
The 'Hunger Games' actress is smitten with the 47-year-old director and has reportedly invited him to live with her in Los Angeles whenever he is in town as though it is still early days for their romance, she already thinks it is much more serious than her brief 2015 fling with Chris Martin.
A source said: "Although she was initially reluctant to date Darren, he won her over and she's really starting to think he could be the man she's been waiting for.
"It's turning into something serious and she's told friends she could actually see herself settling down with him.
"She says he's different to everyone else she's dated, especially Chris. He was such a commitment-phobe during their time together and their whole relationship felt like one big runaround.
"Unlike him, Darren is mature and grounded."
However, some friends are said to be concerned about the speed the relationship is moving and also the reputation the filmmaker - who has son Henry, 10, with ex-fiancee Rachel Weisz and was previously engaged to producer Brandi-Ann Milbradt - has for being difficult and "nasty".
The source told Grazia magazine: "Darren has a reputation as Hollywood's Mr. Nasty within the industry and friends are worried that he could be equally cut-throat in his personal life.
"He has two broken engagements behind him and they'd hate for Jennifer to wind up hurt.
"She's brushed off any doubts and says she wants to lead with her heart.
"But she's more vulnerable than people realise. Everyone is just hoping that it works out."
