plays a strip club owner with a heart of gold in this week's big-screen musical Rock of Ages
, marking her first film role since 2009's I Can Do Bad All By Myself
Her character Justice offers down-and-out country girl Sherrie (Julianne Hough) a job after her fledgling career takes a downward turn.
Speaking to Digital Spy
, Blige revealed that she hired an acting coach to help her prepare for the role of Justice.
"I was with an acting coach for about a month," she said. "I write notes next to my script, so I can remember things.
"My coach told me to use pictures of things, of me as a child, just different things to make me think about my life."
Defending her character's profession, Blige said: "I don't think she's saying to girls, 'Come and work in my strip club'.
"She's saying, 'This is a rest stop'."Rock of Ages opens on Friday (June 13) in the UK and Sunday (June 15) in the US.
