POTW: Janet Jackson, Chris Brown, Justin Bieber, Taylor Swift

Who more appropriate to write a book about self-love than someone that has fluctuated in weight her entire life and as a result has admitted to disproving of herself because of it in the past? Janet Jackson promoted her book, "True You: A Guide To Finding and Loving Yourself," in New York City on March 19.

Janet Jackson promoted her new self-help book, Chris Brown got some advice from Russell Simmons, Justin Bieber rocked a wig, Taylor Swift shopped at an antique shop, Britney Spears rocked an eclectic outfit, Willow Smith whipped her braids back and forth, and Selena Gomez went from day-wear to evening glam effortlessly. It all happened this week and we've got the pics to prove it.
