X Factor judge Demi Lovato has just signed a multi-book deal with an imprint of Macmillan. The first book, due in November, will be a memoir detailing her struggles with substance abuse.

According to The Hollywood Reporter, the memoir — to be titled Staying Strong: 365 Days a Year — will include revealing tweets Lovato has made about her life, including her stints in rehab and the personal troubles she’s overcome.

The book is part of an exceptionally busy fall for the 21-year-old former Disney Channel star, who will also be seen alongside Simon Cowell during her second season on The X Factor as well appearing in an upcoming multi-episode story arc on Glee.
