"Right now it's a little sad but I'm enjoying it... it's the death of Malcolm, the death of Martin and the women trying to be strong and get through it," Blige told Billboard of the early screen tests and makeup work she's already done to look the part. Shooting for the biopic, which will air on Lifetime, began on Tuesday.
Having previously acted in this summer's "Rock of Ages," where she sang a standout cover of Pat Benatar's "Shadows of the Night," she clearly seems to have caught the acting bug.
"I've really been enjoying the whole experience," she said. "It's a lot of long days and months and weeks and you know, I'm working my way through it."
In August, NBC announced Blige would be joining the new season of "The Voice" as mentor to Adam Levine's singers. The R&B star has nine Grammy Awards to her name and recently celebrated the 20th anniversary of her landmark album "What's the 411?".
Blige performed over the weekend at the iHeartRadio Music Festival in Las Vegas, where she paired up with Prince for a memorable version of his "Nothing Compares 2 U." Watch it here.
