Janet Jackson to dish about her weight in a new book

Of all the celebrities who we've seen yo-yo from super-slim to not-so-skinny and back to slim, Janet Jackson has definitely earned some attention in her long career as a superstar. And she's going to tell us all about her weight-loss woes in a new book, according to People Magazine.

She says of the book, "[I'm] really coming from the soul with it, and what I was going through at different times in my life and what possibly brought it about for myself." And besides being soul-baring, the book will also be helpful -- it will contain a thorough look into Janet's nutrition.

Janet felt the need to write the book after realizing last year that she had put on 60lbs. Those pounds seem to be gone now -- she looks fabulous!
