Demi Lovato has announced her newest endeavor: an eBook.

The 20-year-old singer and X Factor judge shared the news on her Twitter page.

"I have an eBook coming out. Exclusively for iPad. Aaaand you can pre-order it now," she wrote on Tuesday.

The eBook, titled Demi, is exepected for release on June 11. It will contain unseen videos, personal photos, and footage of the singer while she was in the process of recording her new album, according to the pre-order page on iTunes.

The singer has seen success with her fourth studio album, Demi, which was released on May 14. It peaked at No. 3 on the Billboard Hot 200 charts. The album's lead single Heart Attack is also a top 10 on the charts. The track has become her second most successful song to date. Her first was the 2011 ballad Skyscraper, which appears on her third studio album Unbroken.

The album has also been embraced overseas. It is top 10 in the U.K., which is reportedly her most successful position in the area to date.

"It's funny, you can be on people's radar but if you don't put out music they like then they won't buy your album, whether you have 13 million Twitter followers or not," she told the website in a May interview. "I'm sure X Factor helped but I believe the album has a bigger sound as a whole. I didn't just want to appeal to my US fans - I'm going for the whole global thing now."

The star is also holding a free concert at Prochester Hall in London on May 31, according to her website. The free show will be filmed and aired on VEVO.
