Lily Collins lost a lot of weight for her role as a woman battling anorexia and she says a friend of hers complimented her on the weight loss.

The 28-year-old actress opened up about the moment in an interview with The Edit.

“I was leaving my apartment one day and someone I’ve known for a long time, my mom’s age, said to me, ‘Oh, wow, look at you!’” Lily said. “I tried to explain [I had lost weight for a role] and she goes, ‘No! I want to know what you’re doing, you look great!’ I got into the car with my mom and said, “That is why the problem exists.”

Lily‘s movie To The Bone will be released on Netflix on July 14.
