Michelle Obama isn't the only one with a December Glamour cover. She shares that honor with Rihanna, who speaks in the magazine about Chris Brown, that photo, and fashion:
In the first two years of my career, there were a lot of restraints on what I could do. I couldn’t wear certain colors of lipstick, like bright pink, dark pink or red; [my lips] had to be natural. Eventually, I stopped communicating with certain people at the label, and did exactly what I wanted to do. And that was to cut my hair, dye it black, change my clothes, change my sound. Really to just express myself ... My hairdresser just said, “I don’t feel like doing your hair anymore — I want to cut it.” I was like, Finally!
In other words, she became a diva.
