Demi Lovato signs multi-book deal, including memoir

Demi Lovato's latest project will be put down on pages.

The singer, actress and "The X Factor" judge has agreed to a multi-book deal with Feiwel and Friends. The publisher, an imprint of Macmillan, announced the deal Monday.

The first book features tweets she had written about her life. It's called "Staying Strong: 365 Days a Year" and comes out Nov. 19.

The publisher describes the book as "a powerful 365-day collection of Demi's most honest, brave and hopeful insights," featuring "her own words, with quotes that inspire her, as well as personal reflections and goals."

Lovato also plans a memoir. The 21-year-old superstar has openly struggled with drug addiction and other personal troubles, some of which she has described on Twitter.

"One of the things that's helped me in my recovery is taking every day one day at a time, and I'm a firm believer in starting off the day right with an inspirational quote and sort of a morning meditation," she said in a video Monday. "So I've put together 365 of my favorite quotes and a little morning meditation for everybody. It's something I'm excited about, I hope you all like it and I hope that it inspires you to be staying strong."

Lovato will be seen this fall on several episodes of "Glee" and is in her second year on "The X Factor."
