Machine Gun Kelly attends the premiere of the movie ‘Good Mourning’

Speaking with PEOPLE at the premiere event, Kelly said that directing his fiancée in the film was a collaboration between both stars.

“She didn’t let me lead her character too much in any direction. She was like ‘I got this. I understand what this character is,’ " he explained. “She improvised and brought [her character] Kennedy to life, and I’ve heard a lot of people say that that’s their favorite character in the movie.”

“I’ll always collaborate with Megan,” theMainstream Selloutmusician added. “I’m madly in love with her — and I’m also a fan.”

“Every line that people wanted to keep in the editing station that she had said was stuff that she actually had said to me in real life,” he detailed. “She was like, ‘You’re 30. It’s time to grow up.’ "

Starring in the movie, Kelly added, also allows himself to show audiences another side of himself.

“I think there’s a Machine Gun Kelly persona that people have married themselves to, and the character that I play in the movie, London, is a vulnerable humanized version of who I really am,” he said.

Good Mourninghits theaters and will be available on-demand May 20.
