The former couple, who parted ways after having trouble maintaining the relation because of busy schedules, were spotted getting cosy on a dinner date, reported Aceshowbiz.
A source said that "The Hunger Games" actress wanted to be back with Hoult because she felt comfortable around him.
"It's a work in progress. There is genuine love between the two and she feels safe with him since he was there before she blew up to this big star."
The couple sparked rumours that they were dating again after having dinner together at The Little Door restaurant in West Hollywood, California.
An eyewitness said that they had "a nice time together", cuddling at their table.
