Janet Jackson reveals that she "never, ever felt attractive" and that she is still grappling with the untimely death of her brother, Michael, in an exclusive interview with Meredith Vieira on the 'Today' show and Dateline NBC.

While discussing her new book, 'True You: A Journey to Finding and Loving Yourself,' Jackson talks about her troubled childhood, her relationship with her famous family and her lifelong struggle with her self-esteem and her weight.

In the book, which debuts Feb. 15, Jackson writes that even while her hit album, 'Rhythm Nation,' was topping the charts, "I hated what I saw in the mirror. I would literally bang my head against the wall because I felt so ugly."
