Janet Jackson has been a fixture in the music, film and television industries for over three decades, and the star can now add "author" to her resume, thanks to her upcoming book, 'True You.'

Jackson, who has struggled with her weight in the past, talked to ABC News about her reasons for writing the book and how she's come to terms with her looks.

Jackson skyrocketed to fame as Penny on the sitcom 'Good Times,' and the part coincided with her early development. "On our first day of shooting they bound my chest because they thought my breasts were too big. It made me feel that the way that I am, it's not good enough," she says.

The singer, who stars in Tyler Perry's upcoming film 'For Colored Girls', says she penned her book to clue fans in on how she regained her svelte silhouette. "Everyone wanted to know about the weight loss, the weight gain -- how do I do it ... It's just talking about my routine, my workout regimen, my nutrition. I wanted to talk about it."
